Feat v0.3.7 package audit

- Fix 6 chat-extension manifests: "name" → "title" (was blocking install)
- Add "type": "surface" to hello-dashboard, icd-test-runner, sdk-test-runner
- Add dormant status to packages schema (SQLite + Postgres)
- Installer auto-detects requires: ["chat"] → sets dormant + disabled
- Enable endpoint returns 409 for dormant packages
- Relax dependency check: pending_review libraries allowed
- Admin UI: dormant badge, disabled Enable button, Dormant stat card
- 4 new handler tests (143 total passing)
- Docker audit: all 16 packages install correctly
