weishu 6f1dc23d77 feat(android): auth + HapiApi transport (B-M1b)
:core:data auth + API transport for track B M1:

- auth/: JwtPeek (unverified {uid,ns,exp} peek for proactive refresh),
  CredentialStore interface + EncryptedPrefsCredentialStore
  (security-crypto) + in-memory impl, HubUrls origin normalization,
  HubRegistry (ordered multi-hub roster + active hub behind a storage
  seam), AuthInterceptor + single-flight TokenAuthenticator (401 ->
  re-exchange -> retry once, Mutex single-flight, terminal AuthEvents,
  ensureFreshToken() for SSE pre-connect)
- api/: HapiApi (plain OkHttp + kotlinx.serialization, one suspend fun
  per v1 endpoint incl. generated-image bytes + multipart transcription
  helper), ApiError with (status, code) per errors.md
- HubSession: per-hub factory wiring clients (timeouts, auth decoration,
  256 MB image cache), DI-free
- :core:protocol wire/: request DTOs (ApiRequests.kt) + response DTOs
  (auth, health, resume/reopen, cancel/steer/queued-state, spawn,
  slash-commands/skills, machine list-directory/paths-exists, uploads,
  transcription)
- tests: 45 unit tests (MockWebServer) — refresh/retry-once, concurrent
  single-flight, terminal 401 paths, ApiError code mapping, request
  shapes (cursors+epoch, deliveryMode, nested answers, explicit nulls),
