Addresses the stability + test-coverage warnings from the #119 review:
- git-http-backend.service.ts: add `'error'` handlers to child.stdout/stderr. An
EventEmitter 'error' with no listener (e.g. EPIPE when the client aborts
mid-response) is rethrown by Node as an uncaught exception and crashes the
process; now swallowed + logged (never echoed to the client).
- TEST INFRA: a jest setupFile shims `navigator`/`MessageChannel` for the `node`
testEnvironment. react-dom@18 reads `navigator` at module-init (pulled in via
@docmost/editor-ext -> @tiptap/react), so every spec transitively importing the
conversion engine — including git-http.service.spec.ts — previously FAILED TO
LOAD ("navigator is not defined") and ran ZERO tests. With the shim those specs
now run (git-sync integration: 11 suites / 133 tests green).
- git-http.service.spec.ts: cover the 503 lock-held push path — `ingestExternalPush`
rejecting `GitSyncLockHeldError` -> 503 + Retry-After + "git-sync busy, retry",
no double header write (+ the already-headers-sent no-rewrite path).
- git-http-backend.service.spec.ts: unit-test run() — child 'error'/'close' before
headers -> 500; normal CGI parse+stream; stdout/stderr 'error' (EPIPE) swallowed;
synchronous spawn throw -> 500.
- page-change.listener.ts: implement OnModuleDestroy to clearTimeout all pending
debounce timers on shutdown (+ test).
- .env.example: vaults are non-bare working repos, not "bare repos".
