27aa40f65e fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ directory (#3175) 
* test(#3023): failing-first guard — pi must not stage hooks in its reserved dir

pi reserves <configDir>/hooks as its deprecated extension location and warns
on every startup when it exists. Assert a pi install stages the shared hook
bundle under gsd-hooks/ instead, manifests it there, and never creates hooks/.

Also adds pi to the local-scope dir table in install-shared.cjs: pi was in
RUNTIME_META but not LOCAL_DIR_NAME, so scope:'local' resolved
path.join(root, undefined) and no local pi install could be exercised.

Fails before the fix. Verified via the remote runner.

* fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ dir

pi reserves <configDir>/hooks as its now-deprecated extension location and
warns on every startup when that directory merely exists — checkDeprecatedExtensionDirs()
guards the warning with a bare existsSync(), unlike its tools/ sibling. GSD staged
its shared hook bundle exactly there, and pi's advised remediation (move it to
extensions/) would break the adapter's paths and expose GSD's .js helpers to pi's
extension auto-discovery.

The bundle directory name is now runtime-descriptor-driven: hostBehaviors
.sharedHooksDirName, defaulting to 'hooks' so all 18 other runtimes are
byte-identical. pi sets 'gsd-hooks'. The name is validated as a single path
segment — separators, dot-only segments, trailing dots, absolute paths, NUL,
and Windows reserved device names all fall back to the default, because the
value is joined onto a user's config root and written to.

Renamed in place rather than relocated: hook scripts resolve siblings via
__dirname/.., so a depth change would silently break them.

- install / uninstall / manifest sites all read the resolved name
- pi/gsd.cjs probes gsd-hooks then hooks, so dev checkouts and half-upgraded
  trees still resolve; the never-throws contract is preserved
- new migration 009 retires the legacy pi hooks/ dir on upgrade, using a new
  non-recursive remove-empty-dir engine primitive (rmdirSync only,
  symlink-refusing, containment-guarded); ADR-0008 amended accordingly
- fixes two latent name-dependencies the rename exposed: the stale-hook scan
  and the injection scanner's self-exclusion both hardcoded 'hooks'

Verified on the remote runner.

Closes #3023

* fix(#3023): close review findings and align emitted provenance with the rename

Adversarial review found two defects, and the remote runner found four
failure clusters. All fixed here.

Review BLOCKER — detect-custom-files was blind to the renamed bundle.
GSD_PREFIX_MANAGED_DIRS in gsd-tools.cjs hardcoded 'hooks', so for pi the
whole gsd-hooks/ tree was invisible to the custom-file scan and user-added
files there were never backed up before the next update's clean-install wipe.
The dir set now resolves via the .gsd-runtime marker plus the shipped
capability registry (never bin/install.js, which is not shipped into installed
trees), and falls back to scanning every known candidate when the runtime
cannot be determined — over-scanning is safe, under-scanning is the data loss.

Review MAJOR — the pi adapter bound to an empty bundle. resolveSharedHooksDir
accepted any directory, so an interrupted install left gsd-hooks/ winning over
a fully-staged legacy hooks/ and every hook silently no-opped. A candidate now
qualifies only if it is non-empty.

Remote-runner clusters:
- emitted-provenance had no rule for the gsd-hooks/ family; added two pi-scoped
  rules pointing at the same sources the existing hooks/ rules use. The table is
  total, so an unattributed family is a hard failure by design.
- pi tests in install-minimal-hooks and the install integration suite asserted
  the old layout; updated to derive the dir name from the descriptor rather than
  hardcoding either name.
- 19 unrelated-looking failures on node22 only were a leaked fs mock: t.after()
  runs in registration order, cleanup was registered before mock.restoreAll(),
  and node22's JS rimraf calls the public fs.rmdirSync while node24's native
  path does not — so the EACCES stub leaked process-wide on one lane. Restore
  now runs first.

Verified on the remote runner.

* fix(#3023): honor PI_CODING_AGENT_DIR, ack the rename ripple, fix expandTilde

pi resolves its agent dir as PI_CODING_AGENT_DIR ?? ~/<CONFIG_DIR_NAME>/agent
(packages/coding-agent/src/config.ts). GSD's pi descriptor declared an empty
configHome.env, so a user with that variable set had GSD installed where pi
never looks. Added the env name; the dot-home-nested resolver already handled
the override, so no resolver logic changed.

Also fixes expandTilde in the shared runtime-homes resolver, found while adding
that: it hardcoded os.homedir() and ignored the opts.home every caller threads,
so EVERY runtime's tilde-valued env override (claude, antigravity, windsurf, pi)
silently resolved against the real home. That is a correctness bug and a
test-escape hazard — a sandboxed test asserting on a tilde override reached the
developer's actual home directory. Now threaded through every branch; behavior
with no injected home is unchanged.

Adds the emitted-drift ack fragment for the 58 pi paths whose emitted location
moved with the rename. The provenance rules satisfy the totality gate; the
differential gate needs the ack because the hook sources are byte-unchanged —
only the installer's target directory moved. The two hook files this branch
genuinely edits stay attributed and are not double-acked.

Note on piConfig.configDir: it is read from pi's OWN installed package.json
(getPackageDir walks up from pi's __dirname), alongside piConfig.name — a
white-label setting for a redistributed pi fork, not a per-project user setting.
Documented accordingly rather than treated as an unsupported override.

Verified on the remote runner.

* fix(#3023): reject blank env overrides, pin adapter/descriptor parity

Three review findings, all fixed.

A whitespace-only config-dir override was accepted verbatim: the guard was
`if (val)`, falsy only for the empty string, so PI_CODING_AGENT_DIR='   '
resolved to a literal three-space directory name instead of falling back to the
descriptor default. Fixed across every env-consuming branch — dot-home,
dot-home-nested, all three xdg steps, and generic-agents-root — not just pi's.
Non-blank values are still never trimmed, so '~/My Agent Dir' keeps working.

pi/gsd.cjs's probe list and the descriptor were two independent sources of truth
for the bundle directory name; a future rename would have desynced them silently
and left every pi hook quiet with no error. The probe list stays deliberate — it
must resolve in a dev checkout and a half-upgraded tree, where the registry's
answer would be wrong — so this adds the parity assertion the repo's
generative-fix-divergence rule calls for: the descriptor value must be the FIRST
candidate, and the default must remain present.

Changeset body rewritten to cover the two later user-facing fixes it had not
caught up with.

Verified on the remote runner.

* chore(#3023): backfill changeset PR number

* fix(#3023): anchor injection-scan patterns and fix a macOS detection hole

CI's security job flagged CONTEXT.md:124 — pre-existing prose reading 'not the
same fact as a genuinely empty or absent one'. The match was the 'act as a'
INSIDE 'f-act as a': the pattern had no left word boundary, so any word ending
in act tripped it (fact, impact, contract, artifact, interact, redact,
abstract). My four-line CONTEXT.md edit dragged the latent false positive into
this PR because the scan is diff-scoped by file but reads whole files. Anchored
with (^|[^[:alnum:]]) rather than rewording maintainer-owned prose, which would
have left the class alive for the next PR touching any file saying 'fact as a'.

Auditing the rest of the list for the same class surfaced a real detection hole:
the eval/exec/Function patterns matched a quote via \x27, a GNU-grep-only hex
escape. BSD/macOS grep reads it as four literal characters, so single-quoted
eval('...')/exec('...') payloads were NEVER detected there while passing on
GNU-grep CI. Replaced with a literal apostrophe class.

Boundaries were added only where a real word-suffix collision exists; exec,
jailbreak, developer mode and the role-manipulation family were audited and
deliberately left unanchored. 22 new cases cover both directions — the false
positives now scan clean, and every real payload still fires, including the
quote/punctuation/start-of-line boundary forms.

Also builds this branch's injection test fixture at runtime instead of carrying
the literal phrase, so the payload keeps its teeth without tripping the scan.

Verified on the remote runner.

e0f969af6a refactor(#2246): centralize cross-platform path-separator handling (toPosixPath / toNativePath / posixNormalize) (#2247) 
Replace every open-coded separator translation across the installer/hooks
source with named, tested seams in shell-command-projection.cts (the platform
seam), removing all hardcoded `/`+`\` from path handling:

- toPosixPath(p)   — this machine's native path → POSIX (running-OS relative;
                     for local filesystem paths).
- toNativePath(p)  — POSIX → native (collapses the win32 `/\//g,'\\'` ternary).
- posixNormalize(p)— unconditional `\`→`/`, OS-independent; for emitting paths
                     to a POSIX/bash TARGET (which may differ from the running
                     OS) and for parsing mixed-separator input.

core-utils.toPosixPath now delegates to the seam, so its 20+ existing consumers
resolve to one implementation; no duplicate helper.

- ~47 sites across runtime-hooks-surface, runtime-artifact-conversion,
  runtime-artifact-install-plan, drift, init, worktree-safety,
  installer-migrations, installer-migration-authoring, install-engine, surface,
  verify, runtime-artifact-layout, schema-detect, check-command-router.
- Closes the latent POSIX-literal-backslash corruption class (the regex form
  corrupts a POSIX path containing a literal backslash; split(path.sep) does not).
- New unit + fast-check property tests for all three helpers.

Closes #2246

cdd78bd2aa fix(#670): self-healing recovery for installer-migration checksum drift (#675) 
Editing the body of an already-released installer migration drifts its computed
checksum (it hashes plan.toString()). The integrity guard then hard-aborted
every prior install on upgrade with "applied migration checksum changed" — a
100% reproducible blocker (v1.3.0, all platforms).

Already-applied migrations are filtered out of `pending` and never re-run, so
a drifted checksum is functionally inert. ADR-0008 anticipates checksum-mismatch
state as something the install-state layer must handle gracefully (plan -> apply
-> recover/report), not abort on.

This supersedes the published-checksum allowlist merged in #674 (per-release
maintenance debt — every historical checksum hand-pinned, still throws for any
unregistered value) with a general, self-healing recovery:

- Replace the throwing guard with non-fatal `collectAppliedChecksumDrift`,
  surfaced on `plan.checksumDrift`.
- Reconcile drifted stored checksums durably on the next state write
  (`reconcileDriftedChecksums`), idempotently (no perpetual writes).
- Relocate the "shipped migration bodies are immutable" rule to a CI baseline
  test that locks every shipped migration's checksum and fails on body drift —
  where #615 should have been caught, instead of blocking users.

Removes #674's legacyChecksums field, per-migration checksum pins,
published-checksums.json fixture, and compat test.

Fixes #670

df04aae5e4 enhancement(#537): migrate all hand-written bin/lib/*.cjs to TypeScript source of truth (ADR-457) (#602) 
* enhancement(#537): migrate code-review-flags to TS source of truth

Collapse the hand-written get-shit-done/bin/lib/code-review-flags.cjs to a
TypeScript source of truth (src/code-review-flags.cts), compiled by tsc to a
gitignored .cjs build artifact at the same path, per ADR-457 (build-at-publish).
Second module after the semver-compare pilot (#541).

Behaviour is preserved byte-for-behaviour (characterization test added in
tests/code-review-flags.test.cjs locks the parser quirks). Adds compile-time
type checking: CodeReviewFlags interface + CodeReviewWorkflow literal union.
The require() path is unchanged, so code-review.md and the bug-3727 test keep
working. The emitted .cjs is gitignored and eslint-ignored, mirroring the pilot.

* enhancement(#537): migrate 9 leaf bin/lib modules to TS source of truth

ADR-457 build-at-publish, batch 1 (pure leaf modules, 0 sibling-deps):
001-legacy-orphan-files, context-utilization, redaction, artifacts,
command-arg-projection, clock, ui-safety-gate, review-reviewer-selection,
clusters. Each moves to src/*.cts (strict TS, typed), compiled by tsc to a
gitignored .cjs at the same require() path; behaviour preserved byte-for-
behaviour. Adds src/node-globals.d.ts (minimal ambient shim; "types":[]).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* chore(#537): add @types/node, drop hand-rolled node-globals shim

ADR-457 migration infra: replace the temporary src/node-globals.d.ts ambient
shim with @types/node@22 + "types":["node"] in tsconfig.build.json. Unblocks
migrating the ~49 remaining bin/lib modules that use node:fs/path/os/
child_process. Build + full suite (3030 pass) + lint all green; no .cts type
changes were needed (real Node types matched the shim).

* enhancement(#537): migrate 9 more bin/lib modules to TS (batch 2)

ADR-457 build-at-publish. Clean leaves: installer-migration-report,
prompt-budget. Type-error-prone leaves (were tsconfig.lint-excluded; now
strict-typed and removed from that exclude list): secrets, phase-lifecycle,
workstream-name-policy, decisions, validate, schema-detect. Plus
runtime-name-policy. Strict type fixes narrow unknown->concrete domain types
(no any/ts-ignore); behaviour preserved. Full suite green, lint 0 errors.

* enhancement(#537): migrate runtime-slash to TS (cross-import proof)

ADR-457. First cross-module TS->TS import: src/runtime-slash.cts imports
./runtime-name-policy.cjs and tsc resolves the sibling .cts types under strict
(no declaration files; NodeNext .cjs->.cts mapping), emitting a correct
require("./runtime-name-policy.cjs"). Confirms the recipe for coupled modules,
which must be migrated in dependency order (leaves-up). Suite green, lint clean.

ADR-457 build-at-publish, Wave-1 leaves: event, workstream-inventory-builder,
plan-scan, fallow-runner, project-root, installer-migration-authoring,
update-context, 000-first-time-baseline, runtime-homes, model-catalog. Strict
typing fixed real issues (narrowing unknown, qualified fs/path calls, removed
unnecessary casts); plan-scan/project-root/workstream-inventory-builder dropped
from tsconfig.lint exclude. Behaviour preserved; suite green, lint 0 errors.

* enhancement(#537): migrate 5 large Wave-1 leaves to TS (batch 4)

ADR-457 build-at-publish: configuration, state-document, shell-command-
projection (42 dependents), security, command-aliases. shell-command-
projection keeps a namespace child_process import for mock-intercept
testability. loadConfig/migrateOnDisk emit synchronously (every caller uses
them sync; the one awaited migrateOnDisk caller tolerates a non-Promise) —
full suite (3030 pass) confirms behaviour preserved. configuration/
state-document/command-aliases dropped from tsconfig.lint exclude. Also fixes
the malformed batch-3 changeset frontmatter (type/pr) that failed lint:docs.

ADR-457 build-at-publish: config-schema, model-profiles,
002-codex-legacy-hooks-json, logger, active-workstream-store, adr-parser.
First batch importing already-migrated siblings (configuration, model-catalog,
shell-command-projection, redaction, security) via ./sibling.cjs specifiers.
Strict type narrowing (typeof guards over String(unknown)); behaviour
preserved; suite 3030 pass, lint 0 errors.

* enhancement(#537): migrate 5 large Wave-2 modules to TS (batch 6)

ADR-457 build-at-publish: graphify, install-profiles, intel,
installer-migrations, worktree-safety. installer-migrations preserves its
dynamic require() loader for numbered migration modules (scoped lint
suppressions). Strict typing (typeof guards over String(unknown)); behaviour
preserved; suite 3030 pass, lint 0 errors. Wave 2 complete.

* enhancement(#537): migrate Wave-3 modules to TS (batch 7)

ADR-457 build-at-publish: planning-workspace, runtime-artifact-layout,
command-routing-hub, drift. Uses `import x = require()` for export= siblings;
drift's lazy require of runtime-slash hoisted to a top-level import (verified
non-circular). Behaviour preserved; suite 3030 pass, lint 0 errors.

* enhancement(#537): migrate small Wave-4 modules to TS (batch 8)

ADR-457 build-at-publish: cjs-command-router-adapter, phase-command-router,
surface, roadmap-upgrade. Typed the hub router handler results as the HubResult
discriminated union; surface drops 4 genuinely-unused imports. Behaviour
preserved; suite 3030 pass, lint 0 errors.

* enhancement(#537): migrate core hub (2.5k LOC, 68 dependents) to TS (batch 9)

ADR-457 build-at-publish: get-shit-done/bin/lib/core.cjs -> src/core.cts,
preserving all 63 exports via export=. All sibling deps already migrated
(shell-command-projection, model-profiles, model-catalog, worktree-safety,
planning-workspace, project-root, configuration, config-schema). Strict types,
no any/ts-ignore; config-schema lazy require hoisted (non-circular). Behaviour
preserved (independently verified: core's shard 3030 pass / 0 fail).

* test(#537): make ESLint-coverage + test-sprawl checks migration-aware

#551 test hardcoded 12 now-migrated modules as "hand-written, must be linted";
that invariant is obsoleted by the ADR-457 migration. Rewrite it to a
filesystem-driven invariant that holds at every stage: a bin/lib/*.cjs must be
eslint-ignored IFF it has a src/*.cts source (tsc-generated), else linted
(covers package-identity, which has no TS source). Also eslint-ignore
config-types.cjs (has a src counterpart) and drop the redundant
tests/clock.test.cjs (clock already covered by clock-seam + bug-474 tests),
which tripped the lint-test-file-count ratchet.

* enhancement(#537): migrate 9 Wave-5 router/inventory modules to TS (batch 10)

ADR-457 build-at-publish: phases/verify/init/agent/task/validate/roadmap/state
command routers + workstream-inventory. Router handler results typed against
core's exported shapes; behaviour preserved (caught+fixed a --verify boolean
flag regression mid-migration). Full suite green across all shards (only the 4
local gpg-env changeset-notes failures remain; CI passes them).

* enhancement(#537): migrate 7 Wave-5 modules to TS (batch 11)

ADR-457 build-at-publish: gap-checker, docs, check-command-router, frontmatter,
learnings, gsd2-import, profile-pipeline. Behaviour preserved; full suite green
across all shards (only the 4 local gpg-env failures remain). Also broadens
atomic-write-coverage.test.cjs to accept the tsc-compiled namespace-import form
while still asserting platformWriteSync is called (safety guard intact).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* enhancement(#537): migrate config + profile-output to TS (batch 12)

ADR-457 build-at-publish: config (729 LOC), profile-output (1142 LOC). All
exports preserved; cmdMigrateConfig de-asynced (migrateOnDisk is sync, awaited
caller tolerates it). Behaviour preserved; suite green across all shards
(only the 4 local gpg-env failures). Wave 5 complete.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* enhancement(#537): migrate 5 Wave-6 modules to TS (batch 13)

ADR-457 build-at-publish: template, uat, workstream, roadmap, audit. Behaviour

Suite green across all shards (only the 4 local gpg-env failures).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* enhancement(#537): migrate commands + state hubs to TS (batch 14)

ADR-457 build-at-publish: commands (1305 LOC), state (2074 LOC, 17 dependents).
All exports preserved; inner requires kept non-hoisted where load-order matters
(install.js, per-call security); acquireStateLock cast inlined to preserve the
err.code source token a structural test inspects. Behaviour preserved; suite
green across all shards (only the 4 local gpg-env failures). Wave 6 complete.

* enhancement(#537): migrate milestone to TS (batch 15a, hand-authored)

ADR-457 build-at-publish: milestone -> src/milestone.cts. Authored directly
(subagent capacity was unavailable). Also relaxes core.output()'s 3rd param to
optional, matching its real always-optional call contract (unblocks remaining
2-arg output callers). Behaviour preserved; suite green across all shards
(only the 4 local gpg-env failures).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* enhancement(#537): migrate phase, verify, init to TS (batch 15, final modules)

ADR-457 build-at-publish, Wave 7 (the last hubs): phase (1608 LOC), verify
(1615), init (2113). Adds src/package-identity.d.cts so verify can import the
permanently value-baked package-identity.cjs under strict TS.

Fixes two regressions the migration introduced in verify: restore
cmdValidateHealth's `return result` (callers/tests read result.warnings — it is
NOT side-effect-only), and make the bug-3384 source-pattern test tolerant of the
tsc-compiled bracket-notation form of the git_list_failed->W020 branch (behaviour
intact). Full suite green across all shards (only the 4 local gpg-env failures);
lint 0 errors. All 86 migratable bin/lib modules are now TypeScript sources.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* chore(#537): finalize ADR-457 migration — retire tsconfig.lint.json

All hand-written bin/lib/*.cjs are now src/*.cts sources, so the checkJs
stopgap tsconfig.lint.json (unused; not wired into eslint, scripts, or CI) is
deleted per ADR-457's final step. Also gitignore the tsc-generated
config-types.cjs (was still committed) for consistency with every other
emitted artifact. package-identity.cjs stays value-baked (declared via
src/package-identity.d.cts). Suite green; #551 ESLint-coverage test green.

* fix(#537): add prepare script so unpacked/git installs build bin/lib artifacts

ADR-457 build-at-publish: bin/lib/*.cjs are now gitignored, built by tsc. The
prepack/prepublishOnly hooks cover `npm pack`/publish, but `npm install -g
<dir>` and git installs run the `prepare` lifecycle — which was missing — so the
unpacked install shipped without the compiled .cjs and failed at startup with
"Cannot find module './lib/core.cjs'" (caught by the smoke-unpacked CI job).
Add `prepare` mirroring prepublishOnly (build:lib + build:hooks). prepare does
NOT run for registry consumers (they get the pre-built tarball), only for
source/local/pack installs.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(#537): make CI build/lockfile checks work with gitignored bin/lib artifacts

ADR-457 build-at-publish exposed two CI assumptions that bin/lib/*.cjs are
always present on disk:
- check:env's lockfile-sync ran `npm ci --dry-run`, which now triggers the
  `prepare` build (tsc) — but it runs before deps are installed, so tsc is
  absent and it misreported the lockfile as out of sync. Add --ignore-scripts
  (a lockfile check must not build).
- the lint-tests job installs with --ignore-scripts (no prepare build), but
  lint:skill-deps require()s the built install-profiles.cjs. Add an explicit
  `npm run build:lib` step after install.

* fix(#537): narrow prepare to build:lib only (unbreak packed-smoke pack step)

prepare running build:hooks emitted "✓ Copying ..." stdout during `npm pack`,
which the install-smoke "Pack root tarball" step captures into $GITHUB_OUTPUT —
breaking it with "Invalid format". build:lib (tsc) is silent on success and is
all the unpacked/source install needs (the smoke-unpacked assertions exercise
gsd-tools, i.e. bin/lib, and tolerate hook setup with `|| true`). Matches
prepack. build:hooks still runs on prepublishOnly for real publishes.

* fix(#537): wire Stryker mutation gate to build-at-publish layout

The gate scored 0.00 because it mutated changed bin/lib/*.cjs that (a) were
generated artifacts and (b) included modules with no coverage in the command's
test set. Rework: mutation.yml now derives changed COVERED modules from
src/*.cts and maps them to their built bin/lib/*.cjs; Stryker mutates those
built artifacts with a no-rebuild command (mutating src/*.cts + per-mutant tsc
was ~3x over the 30-min CI budget).

NOTE: with the gate now correctly measuring the covered modules, their actual
mutation score is 42.94% (< break 50) — a pre-existing test-coverage gap
(adr-parser/prompt-budget/etc.), not introduced by this behaviour-preserving
migration. Reaching 50 needs more tests, a threshold/scope change, or a waiver —
a maintainer decision.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* test(#537): raise mutation coverage of covered modules above the 50 gate

Adds focused example-based unit tests that kill surviving mutants in the two
lowest-scoring covered modules:
- tests/prompt-budget.unit.test.cjs (112 tests): 17.9% -> 97.9%
- tests/adr-parser.unit.test.cjs (205 tests): 44.7% -> 89.4%
Both wired into stryker.config.mjs's command. Fresh full run over the 6 covered
modules now scores 82.25% (>= break 50); every covered module is >= 68%.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* enhancement(#537,#609): parallelize mutation gate via dynamic per-module matrix

The serial Stryker run timed out at 30 min once the migration's added tests
made every mutant re-run ~300 tests. Replace it with a dynamic matrix so the
gate completes well under budget — folded into this PR (was tracked as #609)
because it's a prerequisite for this PR's mutation gate to pass.

- scripts/mutation-matrix.cjs: single source of truth (covered-module -> test
  files) computing changed covered modules from git diff -> {has_work, matrix}.
- mutation.yml: detect -> dynamic `matrix: fromJSON(...)` mutate job (one
  parallel shard per changed module, scoped via MUTATION_TEST_CMD to only that
  module's tests, 15-min/shard) -> summary job that KEEPS the legacy check name
  "Stryker mutation score (changed files only)" so branch protection is
  unchanged. Per-shard jobs report as "Stryker (<module>)".
- stryker.config.mjs: commandRunner.command reads MUTATION_TEST_CMD (falls back
  to the full command locally).

Closes #609.

* test(#537,#609): give each mutation shard ≥50% on its own tests; drop blacksmith note

Per-module sharding revealed that active-workstream-store (46.5%) and
frontmatter (7.4%) only cleared 50% in the old serial run via timeout-noise from
the bloated 300-test command; on their own tests they were below the gate. Add
focused unit tests:
- tests/active-workstream-store.unit.test.cjs (115 tests): 46.5% -> 81.9%
- tests/frontmatter.unit.test.cjs (165 tests): 7.4% -> 63.4%
Both wired into scripts/mutation-matrix.cjs (per-module test map) and
stryker.config.mjs DEFAULT_TEST_CMD. All 6 covered modules now clear break:50
with only their own tests (config-schema/context-utilization/prompt-budget/
adr-parser already did). Also removes the leftover blacksmith TODO comment —
GitHub-hosted runners only; speed comes from parallel per-module shards.

* test(#537,#609): strengthen prompt-budget tests to clear the gate on its own tests

prompt-budget scored 39.58% when mutation-tested with ONLY its own tests (the
way the per-module CI shard runs it) — an earlier ~98% reading was inflated by
accidentally running the full multi-module command. Add 96 targeted tests to
tests/prompt-budget.unit.test.cjs (exact note-template text, plan-truncation
arithmetic/percentages, drop-block strings, noteInjected/hardFailed booleans):
scoped score 39.58% -> 68.75% (>= break 50). All 6 covered modules now clear
the gate on their own tests.
