feat(#770): register Claude Code lifecycle hooks (SubagentStop/Stop/PreCompact/FileChanged) (#821)

* feat(#770): register Claude Code lifecycle hooks (SubagentStop/Stop/PreCompact/FileChanged)

Wire three new context-tracking events (SubagentStop, Stop, PreCompact) to
gsd-context-monitor so context-headroom warnings surface at model-stop and
subagent-finalisation moments — not just on PostToolUse.  Add a new
FileChanged hook (gsd-config-reload.js) that hot-reloads .planning/config.json
context mid-session when the user edits it, injecting a config summary as
hookSpecificOutput.additionalContext.  Updates plugin manifest hooks.json,
managed-hooks-registry, installer-migration-report allowlist, and
shell-command-projection cleanup tables.  Tests: 21 new assertions in
enh-770-claude-hook-events.test.cjs; enh-788 and issue-766 test suites updated.

Closes #770

* docs(#770): document newly-registered Claude Code lifecycle hooks

Add a Hook coverage table to the Claude Code npm installer section of
docs/how-to/install-on-your-runtime.md describing SubagentStop, Stop,
PreCompact, and the new FileChanged (gsd-config-reload.js) hook that
hot-reloads .planning/config.json mid-session. Also fixes the changeset
frontmatter (adds type: Added + pr: 821) so docs-lint can consume the
fragment.

* fix(#770): add gsd-config-reload.js to INVENTORY.md and regenerate manifest

The feat commit added hooks/gsd-config-reload.js but did not bump the
Hooks count in docs/INVENTORY.md (14→15) or add the new row, and did not
regenerate docs/INVENTORY-MANIFEST.json. Both inventory-counts and
inventory-manifest-sync tests failed across the full CI matrix.

* fix(#770): make lifecycle-hook tests deterministic on scoped runner

Replace the shared hooks/dist/ ensemble setup (ensureHooksDist /
teardownHooksDist) in the Claude hook tests with per-test isolation:
pre-populate each test's own tmpDir/.claude/hooks/ with stub files and
pass installerMigrations:[] to install() so the first-time-baseline
migration does not remove the stubs before the copy step can run.

Root cause: hooks/dist/ is gitignored and absent on a fresh npm ci.
ensureHooksDist() created it and teardownHooksDist() deleted it, but
with --test-concurrency=4 both test files ran concurrently as separate
Node.js worker processes sharing the same filesystem.  One file's
afterEach teardown deleted hooks/dist/ while the other file's install()
was copying from it, producing an ENOENT (reproduced 2/10 runs locally).

The additional issue: even with pre-placed stubs surviving the copy race,
the 000-first-time-baseline migration classified hooks/gsd-*.js as
bundled-gsd-hook artifacts, auto-removed them, and the copy step never
re-ran (hooks/dist/ absent) — leaving contextMonitorFile missing and all
hook registrations silently skipped (the 'got: []' symptom).

Fix: pre-populate targetDir/hooks/ per-test (isolated temp dir) AND pass
installerMigrations:[] so the baseline scan is skipped.  The Qwen suites
already used this pattern correctly; the Claude suites are aligned to it.

* fix(#770): ship gsd-config-reload.js by adding it to build-hooks HOOKS_TO_COPY

The #770 feature added hooks/gsd-config-reload.js and registered it in
MANAGED_HOOKS, the installer, INVENTORY, and the test EXPECTED_ALL_HOOKS
list — but never added it to scripts/build-hooks.js HOOKS_TO_COPY. As a
result the hook was never copied into hooks/dist/ during the build, so:

  - the hook would never ship to users (real production bug — the
    FileChanged config-reload feature was dead-on-arrival), and
  - install-minimal-hooks.test.cjs #1755 ("all expected hooks are copied
    from hooks/dist/ to target", ".js hooks are executable after copy",
    "manifest contains .js hook entries") failed on any environment with
    a clean checkout (no pre-existing hooks/dist/): coverage, full test
    macos-22/macos-24, test ubuntu-24.

The failures were masked locally only by a stale hooks/dist/ left from a
prior build (build-hooks copies into dist without clearing it). On CI's
fresh `npm ci` there is no dist, so the omission surfaced.

Fix: add 'gsd-config-reload.js' to HOOKS_TO_COPY so build-hooks stages it
into hooks/dist/ alongside the other JS hooks. Verified by removing
hooks/dist/ and rerunning the full suite green (0 fail).

* fix(#770): make config prototype-pollution beforeEach deterministic on scoped runner

Root cause: the #663 and alert-#26 prototype-pollution describe blocks
seeded .planning/config.json in beforeEach via a bare
runGsdTools('config-ensure-section') whose result was discarded. That
command runs in a spawned gsd-tools child; on the scoped CI lane
(--test-concurrency=4, config.test.cjs scheduled alongside the heavy
install/tarball suites that #770 pulled into the targeted set) the child
can be transiently killed under resource pressure (non-zero exit, empty
stderr — an OS-level kill, not an app error). The swallowed failure left
config.json absent, so the first subtest's readConfig() threw ENOENT
opening <tmp>/.planning/config.json. Only 1 of 4 subtests failed,
confirming a per-invocation transient, not a deterministic miss; the full
suite schedules files differently so config.test.cjs did not collide with
those heavy neighbors → passed there.

Fix: add ensureConfigReady(tmpDir) which retries config-ensure-section on
ANY failure or missing file and throws a clear diagnostic if it still
cannot create config.json, then use it in both prototype-pollution
beforeEach blocks. Setup is now deterministic under load; the #663/alert-#26
security assertions are unchanged.

Module owning the explicit per-runtime config-mutation dispatch table for the installer. `resolveRuntimeConfigIntent(runtime)` projects a typed config intent — `installSurface` (`settings-json` | `codex-toml` | `copilot-instructions` | `cline-rules` | `cursor-hooks-json` | `profile-marker-only`), `writesSharedSettings` (the `finishInstall` shared-settings write gate), and `finishPermissionWriter` (`opencode` | `kilo` | none) — that `bin/install.js` dispatches on instead of inline `runtime === '...'` branching. Owns adapter selection only: it performs no filesystem IO and does not execute config mutations (the install/finishInstall handlers and the per-runtime writers do that). Unknown runtimes fail loudly with a `TypeError`, guarded by an `Object.hasOwn` own-property check so prototype-chain keys (`__proto__`, `constructor`) also throw. Realizes the adapter-selection half of the Runtime Install Policy Module boundary. Source: `gsd-core/bin/lib/runtime-config-adapter-registry.cjs`. See ADR-58, #60.
### Claude Code Plugin Manifest Module
Module owning the projection of gsd-core's artifact surfaces (`commands`, `agents`, hooks) onto the Claude Code plugin contract (`.claude-plugin/plugin.json` + `hooks/hooks.json`) — the plugin-contract sibling of the Runtime Artifact Layout Module (which projects the same surfaces onto filesystem placements). Defined mapping: `name`=`binName` (drives the `/gsd-core:` command namespace), `repository`/`homepage`=`repoUrl` (Package Identity Module), `version`/`description`/`license` from `package.json` (`version` is required for `claude plugin validate --strict`), `commands`=`./commands/gsd/`, agents via Claude Code's default `agents/` discovery (the explicit string form is schema-rejected), `hooks`=`./hooks/hooks.json`. The hook projection carries ONLY the always-on subset of the Installer Module's Claude `settings.json` wiring (check-update, context-monitor, prompt-guard, read-guard, worktree-path-guard, read-injection-scanner) via `${CLAUDE_PLUGIN_ROOT}`; config-gated opt-in hooks are excluded because a static manifest cannot honor per-project config gates, and plugin-shipped agents cannot carry hook frontmatter (so all plugin-path hook wiring lives in hooks.json). Additive — the file-copy path (Runtime Artifact Layout / Install Policy / Installer Modules) is unchanged. Conformance is validated by `claude plugin validate --strict` plus the in-repo drift-guard `tests/issue-766-plugin-manifest.test.cjs`. _Avoid_: "the plugin API", "the plugin file" (when you mean the seam). See ADR-766 and Runtime Artifact Layout Module.

### Gemini Extension Package
The repo-root `gemini-extension.json` + `GEMINI.md` pair that projects gsd-core onto the Gemini CLI extension contract, enabling one-step lifecycle management via `gemini extensions install <git-url>` / `update` / `remove` (and `gemini extensions link <path>` for dev). The Gemini-CLI sibling of the Claude Code Plugin Manifest Module — same additive idea, different runtime package format. Defined mapping: `name`=`binName` (`gsd-core`; lowercase-dashes per Gemini's extension naming rule), `version` tracks `package.json` (Gemini's `gemini extensions update` keys off the manifest `version` field), `description` (required by the manifest schema), `contextFileName`=`GEMINI.md` (the extension's context payload, loaded into every Gemini session). Intentionally minimal: no `mcpServers` (gsd-core ships no MCP server). Slash-command / agent / hook projection into the extension (which would require committing the Gemini-format TOML/agent conversions the Installer Module produces at `--gemini` install time) is deferred — the manual `npx gsd-core --gemini` path remains the way to install the `/gsd:*` commands, and is unchanged (additive, no breaking change). Conformance is guarded by the in-repo drift test `tests/issue-775-gemini-extension.test.cjs` (manifest validity, `version`↔`package.json` parity, `contextFileName` existence, `files[]` publication). _Avoid_: "the Gemini plugin" (Gemini calls them extensions, not plugins). See #775, ADR-766, Claude Code Plugin Manifest Module, and Runtime Artifact Layout Module.
