Tom Boucher e242d85c92 fix(#4109): rewrap unquoted DISPATCH_SLUGS-shaped consumption to survive zsh (#4116)
* test(#4109): add zsh regression coverage for gate-check and invoke_reviewers dispatch

Extends tests/review-plan-coverage-manifest.test.cjs to cover the two
DISPATCH_SLUGS consumption sites the existing #3301 coverage-check tests
don't reach: the write_reviews gate-check block (ALL_LANES_SKIPPED /
TOTAL_LANE_FAILURE counting) and invoke_reviewers' dispatch + join loops.
Both extract the real shipped bash from review.md and run it under bash and
zsh, same convention as the existing coverage-check rows. Expected RED under
zsh pre-fix, GREEN post-fix.

* fix(#4109): rewrap unquoted DISPATCH_SLUGS-shaped consumption to survive zsh

Bash word-splits an unquoted scalar on IFS by default; zsh does not (no
setopt SH_WORD_SPLIT anywhere in these files), so a scalar accumulated from
multiple space-separated tokens and then consumed via bare `for x in $VAR`
collapses onto one bogus iteration under zsh whenever it holds 2+ tokens.

Fixes all four review.md sites reported by #4108/#4109 (invoke_reviewers
dispatch + join loops, the gate-check block, and the #3301 coverage-check
block), plus the identical pattern found by a repo-wide sweep in
complete-milestone.md, code-review.md, pr-branch.md, sync-skills.md, and
execute-phase/steps/per-plan-worktree-gate.md. Each site is rewrapped in
unquoted command substitution (`$(printf '%s' "$VAR")`), which re-splits
identically under both shells regardless of SH_WORD_SPLIT — the same
mechanism that already made the accumulator-building loops in these files
shell-safe.

* test(#4109): warn loudly when the zsh probe fails instead of skipping silently

detectShells() drops the zsh test lane whenever a live zsh probe fails (e.g.
on a CI runner without zsh installed), and a dropped lane reads identically
to a passing one in the suite's own output — exactly the blind spot that let
#4109's bug class ship undetected. Both copies of this helper (this file and
its byte-identical duplicate in review-build-prompt-optional-sections.test.cjs)
now emit a greppable console.warn when the probe fails, so a run without zsh
reads as "zsh coverage unknown" rather than "all lanes green".

* ci(#4109): gate workflows/*.md's embedded bash blocks in lint:ci

Adds scripts/lint-workflow-shellcheck.cjs, wired into npm run lint:ci, so
this bug class can't land undetected a third time. Two independent checks
run over every ```bash block in gsd-core/workflows/**/*.md:

- ShellCheck (new `shellcheck` devDependency, downloads and caches the real
  koalaman/shellcheck binary) catches the general unquoted-expansion/
  word-splitting family in argument position. 212 pre-existing findings
  across the tree are absorbed into scripts/lint-workflow-shellcheck-baseline.json
  (matched on {file, code, message}, not line number, so unrelated edits
  elsewhere in a file can't spuriously un-baseline anything) — fixing all of
  them is out of scope for this issue; only NEW findings fail the build.
- A custom structural check specifically for #4109's own shape: ShellCheck
  does not flag a bare `for x in $VAR` word-list — it treats that as an
  intentional idiom under any ruleset (confirmed empirically). This check
  does, and gates the build on any occurrence, with zero tolerance (no
  baseline) since every known site was already swept and fixed on this
  branch.

* test(#4109): update pr-branch cherry-pick loop test anchor for the zsh fix

extractPickLoop()'s PICK_LOOP_MARKER located the create_pr_branch cherry-pick
loop by the literal substring "for HASH in $INCLUDED_COMMITS", which no
longer appears verbatim after this issue's fix rewrapped that loop in
unquoted command substitution. Updates the anchor (and its error message,
now derived from the same constant instead of duplicating stale text) to the
new literal form. No behavior change to the extraction logic itself.

Emitted-Drift-Ack-Growth: review.md — #4109's fix adds explanatory comments at 4 sites; net code is functionally equivalent, comment expansion grows the file
Emitted-Drift-Ack-Growth: complete-milestone.md — #4109's fix adds explanatory comments at 3 sites documenting the zsh word-splitting divergence
Emitted-Drift-Ack-Growth: code-review.md — #4109's fix adds an explanatory comment documenting the zsh word-splitting divergence
Emitted-Drift-Ack-Growth: pr-branch.md — #4109's fix adds explanatory comments at 3 sites (TRANSIENT_DIRS, INCLUDED_COMMITS, FILTER_PATHS)
Emitted-Drift-Ack-Growth: sync-skills.md — #4109's fix adds explanatory comments at 2 sites (CREATE_LIST/UPDATE_LIST, REMOVE_LIST)

* test(#4109): cover lint-workflow-shellcheck parsers + add timeout

Adds tests/lint-workflow-shellcheck.test.cjs covering the hand-rolled
parser/logic functions exported by scripts/lint-workflow-shellcheck.cjs
(stripCommandSubstitutions, stripShellComments, substitutePlaceholders,
extractForLoops, findBareForLoopSplits, findingKey, partitionAgainstBaseline)
that shipped with zero coverage — CLAUDE.md requires at least one fast-check
property test for parsers, included here (bare/braced forms always flagged
naming the variable; quoted/substituted/literal forms never are).

Also bounds runShellcheck's subprocess with a 60s timeout: the `shellcheck`
npm package's own API has no timeout option and internally blocks on a
synchronous spawnSync, so this reimplements the binary resolve/download step
via the package's own exported config/download and calls spawnSync directly
with a native timeout. And guards the CLI entry point with
`if (require.main === module)`, matching this repo's sibling dual-purpose
lint scripts — without it, requiring the module for its exported functions
(as the new test file does) also triggered a live ShellCheck run as a side
effect.

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

Promotion is automatic. The release workflow's finalize job runs:

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty

This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.

Archived fragments

.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
