Add shared RSpaceOfflineRuntime singleton that coordinates IndexedDB
persistence (EncryptedDocStore), WebSocket sync (DocSyncManager), and
in-memory Automerge docs (DocumentManager) for all module web components.
- Phase 0: runtime.ts singleton, shell integration, beforeunload flush
- Phase 1: rstack-offline-indicator status dot in shell header
- Phase 2: service worker stale-while-revalidate for API GETs + offline fallback
- Phase 3: storage-quota.ts with LRU eviction (30d) and quota warnings (70%)
- Phase 4: Tier 1 single-doc modules (rFlows, rCal, rBooks, rSplat)
- Phase 5: Tier 2 multi-doc modules (rNotes, rWork, rInbox, rVote, rTrips, rFiles)
with doc-list-request/response wire protocol for document discovery
- Phase 6: Tier 3 special cases (rCart hybrid, rForum global doc, rSchedule)
Data now loads instantly from IndexedDB, syncs via WebSocket when online,
and remains browsable offline. rNotes migrated from inline Automerge WS
to shared runtime. All modules fall back to REST when runtime unavailable.
