claude_code 32058ff272 feat(offline): PWA shell, Yjs-backed titles, and offline read cache (M0–M2) ...

Implements docs/offline-sync-plan.md milestones M0–M2.

M0 (PWA shell):
- Add vite-plugin-pwa (generateSW, registerType: 'prompt', manifest:false);
  NetworkOnly for /api,/collab,/socket.io, NetworkFirst for GET /api,
  navigateFallback to index.html.
- Register SW via useRegisterSW with a Mantine update prompt; skip
  registration inside Capacitor native WebView (is-capacitor guard).

M1 (harden CRDT body + title into Yjs):
- Lift the per-page Y.Doc/Hocuspocus providers into a shared hook+context so
  body and title editors share one doc.
- Move the page title into a dedicated 'title' Yjs fragment (CRDT, offline-
  tolerant); drop the REST title save. Server persists the title fragment to
  page.title and seeds it for legacy pages (empty-fragment guard); a collab
  rename emits a treeUpdate so other users' tree/breadcrumbs refresh.
- Persist the rebuilt ydoc on the content->ydoc path to neutralize the Yjs
  duplication trap. Add a 3-state sync indicator.

M2 (offline read/navigation):
- Persist React Query to IndexedDB (idb-keyval persister, version buster,
  selected roots only).
- "Make available offline" action warms page, space, tree (root+ancestors+
  children) and comments under exact hook keys, plus the page ydoc.
