WIP: M3 PWA/offline implementation, M4 auth (backend + frontend), D-013 faster-whisper

- M3: hand-rolled service worker (precache + runtime /ort caching), precache
  manifest injection, SW registration/update toast, manifest + generated icons,
  production build script, offline indicator in ModelPicker (D-005/D-007)
- M4 backend: bun:sqlite users/sessions (D-009), Passport local strategy behind
  connect-compat adapter (D-008), /api/auth routes wired into dev+prod serving,
  Bun.password Argon2id, 38 auth tests
- M4 frontend: AuthForms + useAuth + framework-free authClient, session-aware
  header, anonymous-first fail-silent offline handling, 18 client tests
- D-013: server engine (M5) will use faster-whisper via Python sidecar;
  browser side stays Transformers.js (CTranslate2 has no WASM build)
- bun test: 83 pass / tsc --noEmit clean
- Note: M3 doc closeout (WorkBreakdown/Architecture/tests/offline.md) still in
  flight from a background agent; follow-up commit will finish docs
