feat(brain): salience privacy allowlist gate (T17 / D9)
D9 cross-model finding from codex outside voice: salience-sourced digests
can include emotionally-weighted personal pages (family, therapy,
reflection). Pulling those into a coding-review prompt leaks sensitive
context into work-flow reasoning.

fetchSalience now strips entries whose slugs don't match an allowlist
prefix BEFORE writing to the cache file. Default allowlist is
SALIENCE_DEFAULT_ALLOWLIST = ['projects/', 'concepts/', 'gstack/'].
User can extend via:
  gstack-config set salience_allowlist 'projects/,gstack/,concepts/,custom/'
or override with GSTACK_SALIENCE_ALLOWLIST env var.

Digest still records the strip count for transparency. Empty result
emits 'all N entries stripped' note rather than silent absence.

test/salience-allowlist.test.ts: 9 tests covering default permits,
default blocks, empty allowlist, env override, whitespace trimming,
and the invariant that defaults contain nothing sensitive (personal,
family, therapy, reflection, private, medical, health).

feat(brain): concurrent-refresh lockfile dedup (T15 / D3)
When autoplan dispatches 4 planning skills back-to-back and they all hit
a cold-miss on the same digest, only ONE actually fetches from the brain.
The rest dedup via the project-scoped lockfile at
~/.gstack/projects/<slug>/brain-cache/.refresh.lock.

Reuses the 5-min stale-takeover convention from /sync-gbrain. Lock is
taken over when:
  - File is older than CACHE_REFRESH_LOCK_TIMEOUT_MS
  - PID is on the same host and dead (process.kill(pid, 0) fails)
  - Lock file is corrupt (defensive)

withRefreshLock(projectSlug, fn) returns either the callback's value or
the literal 'dedup'. The CLI emits exit code 3 + diagnostic stderr on
dedup, so callers can choose to wait + retry (resolver does this) or
fall through to stale-but-usable behavior.

test/cache-concurrent-refresh.test.ts: 7 tests covering acquire/release,
stale-takeover, dead-PID takeover, corrupt-lock recovery, error-path
release, and cross-project lock location.

feat(brain): gstack-brain-cache CLI (T2a) — core subcommands
bin/gstack-brain-cache: TS CLI with five subcommands:
  get <entity-name> [--project <slug>]
  refresh [--full] [--entity X] [--project <slug>]
  invalidate <entity-name> [--project <slug>]
  digest <entity-slug>
  meta [--project <slug>]

Cache layout per Phase 0.5 design:
  ~/.gstack/brain-cache/                 ← cross-project (user-profile)
  ~/.gstack/projects/<slug>/brain-cache/ ← per-project (everything else)

Per-entity TTL drives staleness; per-entity byte budgets enforce
compression at write time. Atomic writes via tmp+rename. Stale-but-usable
fallback when brain unreachable (returns cached digest with diagnostic
prefix instead of failing). Schema-version mismatch + endpoint switch
both trigger full rebuild for the affected scope (D4 A4).

Fetch+compress paths wired for the 7 entities (user-profile, product,
goals, developer-persona, brand, competitive-intel, recent-decisions,
salience) via gbrain CLI shell-out — works for local PGLite and
local-stdio MCP, transparent over the existing spawnGbrain helper.

Concurrent-refresh dedup (D3 / T15) is a follow-up commit. Salience
allowlist gate (D9 / T17) is a follow-up commit. Bootstrap + lifecycle
subcommands (T2b / T18) are follow-up commits.

test/brain-cache-roundtrip.test.ts: 11 tests covering path resolution,
meta lifecycle, endpoint detection, schema mismatch behavior, and the
four cache states (warm / cold-refreshed / stale-fallback / missing).
