feat(slice-05): /install audit-write integration (Item 4 close-out) (OPR.0.3.2.5)

Closes Item 4. /install handler now writes a BundleAuditRecord at
each apply-mode completion path (completed, partial, failed, caught
error). Plan mode does NOT write (planning doesn't change state).
The history endpoint (GET /api/bundles/history) now surfaces real
records in production usage.

Audit record composition:
- installedAt: new Date().toISOString() at write time
- bundlePath: from request body
- outcome: "success" / "failed" / "partial" mapped from bootstrap status
- targetRigId: from bootstrap result.rigId when present
- targetRigName: from installMeta.rigName (extracted from bundle's rig.yaml)
- daemonVersion: from getDaemonVersion() at call time
- cliVersion: from clientCliVersion (request body field)
- sourceHost: from installMeta.bundleManifest provenance, if present
- archiveHash: not included this commit (operator correlates via
  bundlePath; can be added in a follow-on if needed)

Files touched:
- packages/daemon/src/routes/bundles.ts: extend BundleAuditReader
  import to also import BundleAuditWriter + BundleAuditRecord; new
  writeInstallAudit helper that composes a record + appends via
  BundleAuditWriter. Best-effort: helper has internal try/catch so
  audit-write failures never fail the install response (the install
  has already succeeded or failed; the audit is a side-channel
  record). 4 call sites added at each apply-mode completion branch
- packages/daemon/test/bundle-routes.test.ts: 2 new tests — plan
  mode does NOT write an audit record (history total stays 0);
  apply mode writes a record visible via /history with required
  shape (installedAt, bundlePath, outcome in success/failed/partial,
  daemonVersion). Test isolation via OPENRIG_HOME env override to
  per-test tmpDir

Diff: 2 files, +134 / -1 lines.

Verified:
- 42/42 daemon (was 40; +2 new audit-write integration tests)
- 32/32 bundle-routes; 10/10 bundle-audit
- CLI unchanged (no CLI files touched this commit)
- Discriminator confirmed: temporarily renaming the writeInstallAudit
  function definition to writeInstallAudit_BROKEN causes 2/32
  bundle-routes tests to fail (the two new audit-write tests);
  restoring returns 32/32. (Earlier weak-discriminator attempt only
  flipped 2 of 4 call sites — the catch branch still wrote a "failed"
  outcome which the test accepted; the function-rename discriminator
  is stronger because it removes the symbol entirely.)
- scope-and-versioning sections 1+3 coherence grep clean
- audit-every-layer: zero new module-level constants; writeInstallAudit
  + auditFsOps + bundleAuditPath all call-time reads

Pre-commit discipline applied (banked): git diff --cached --stat
verified +134/-1 across 2 intended files BEFORE commit.

PRD bounce conditions verified:
- No schema bump
- No new SQLite migrations (JSONL only — matches PRD Item 4)
- No event types (audit failures stay side-channel; eventBus surface
  is a future enhancement explicitly out of this commit)
- No core-routing or bootstrap-orchestrator mutation (the bootstrap
  delegation is unchanged; audit-write happens AFTER bootstrap
  returns)
- No sidebar entries touched

Item 4 closes here. Item 4 sub-chain on this branch:
- 0af652dc (Item 4 part 1: audit module, CLEAR)
- b0ae54ad (Item 4 part 2: history route + CLI, CLEAR)
- THIS COMMIT — Item 4 part 3: /install audit-write integration

Slice-05 progress: Items 1+2+3+4 all complete. Remaining: Items 5
(inspector UI + Files browser composition) + 6 (cross-primitive
bundling + gstack HYBRID proof case per orch-ratified decision doc).
Then adversarial QA + orch heavy-verify + LOCAL --no-ff merge.
