v0.2.9-rc.0

What's Changed

Features

• feat(persistence): add IndexedDB persistent queue for UI updates
  • Persist UI update events to IndexedDB before dispatch, enabling reconnecting tabs to catch up on missed events after page refreshes or weak-network reconnections
  • Auto-increment seq field for cursor-based tracking and gap detection
  • Worker exposes getCatchUpEvents(fromSeq) for main thread catch-up with hasGap flag
  • onUIUpdate callback now includes seq for precise progress tracking
  • New onStateGap callback signals when full state refresh is needed

Breaking Changes

• UIUpdateListener signature changed to (event, seq)
• publish() is now async (fire-and-forget pattern recommended)

Tests

• Comprehensive gap detection tests for getCatchUpEvents
• Persistent UI update queue E2E tests
• Worker bridge tests
