* 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.
