Update task task-058

Add proxy endpoints to Cloudflare Worker for AI services, keeping
API credentials server-side for better security architecture.

Changes:
- Add fal.ai proxy endpoints (/api/fal/*) for image generation
- Add RunPod proxy endpoints (/api/runpod/*) for image, video, text, whisper
- Update client code to use proxy pattern:
  - useLiveImage.tsx (fal.ai live image generation)
  - VideoGenShapeUtil.tsx (video generation)
  - ImageGenShapeUtil.tsx (image generation)
  - runpodApi.ts (whisper transcription)
  - llmUtils.ts (LLM text generation)
- Add Environment types for AI service configuration
- Improve Automerge migration: compare shape counts between formats
  to prevent data loss during format conversion

To deploy, set secrets:
  wrangler secret put FAL_API_KEY
  wrangler secret put RUNPOD_API_KEY

 Fixed persistence issue: Modified handlePeerDisconnect to flush pending saves and updated client-side merge strategy in useAutomergeSyncRepo.ts to properly bootstrap from server when local is empty while preserving offline changes
 
 Fixed TypeScript errors in networking module: corrected useSession->useAuth import, added myConnections to NetworkGraph type, fixed GraphEdge type alignment between client and worker
+
+## Investigation Summary (2025-12-25)
+
+**Current Architecture:**
+- Worker: CRDT sync enabled with SyncManager
+- Client: CloudflareNetworkAdapter with binary message support
+- Storage: IndexedDB for offline persistence
+
+**Issue:** Automerge Repo not generating sync messages when `handle.change()` is called. JSON sync workaround in use.
+
+**Suspected Root Cause:**
+The Automerge Repo requires proper peer discovery. The adapter emits `peer-candidate` for server, but Repo may not be establishing proper sync relationship.
+
+**Remaining ACs:**
+- #2 Client-server binary protocol (partially working - needs Repo to generate messages)
+- #3 Deletions persist (needs testing once binary sync works)
+- #4 Concurrent edits merge (needs testing)
+- #6 All functionality works (JSON workaround is functional)
+
+**Next Steps:**
+1. Add debug logging to adapter.send() to verify Repo calls
+2. Check sync states between local peer and server
+3. May need to manually trigger sync or fix Repo configuration
+
+Dec 25: Added debug logging and peer-candidate re-emission fix to CloudflareAdapter.ts
+
+Key fix: Re-emit peer-candidate after documentId is set to trigger Repo sync (timing issue)
+
+Committed and pushed to dev branch - needs testing to verify binary sync is now working

+
+All acceptance criteria implemented:
+
+**AC #1 - Board renders from IndexedDB offline:**
+- Board.tsx line 1225: `isOfflineWithLocalData = !isNetworkOnline && hasStore`
+- Line 1229: `shouldRender = hasStore && (isSynced || isOfflineWithLocalData)`
+
+**AC #2 - Working Offline indicator:**
+- ConnectionStatusIndicator shows 'Working Offline' with purple badge
+- Detailed message explains local caching and auto-sync
+
+**AC #3 - Changes saved locally:**
+- Automerge Repo uses IndexedDBStorageAdapter
+- Changes persisted via handle.change() automatically
+
+**AC #4 - Auto-sync on reconnect:**
+- CloudflareAdapter has networkOnlineHandler/networkOfflineHandler
+- Triggers reconnect when network returns
+
+**AC #5 - No data loss:**
+- CRDT merge semantics preserve all changes
+- JSON sync fallback also handles offline changes
+
+**Manual testing recommended:**
+- Test in airplane mode with browser reload
+- Verify data persists across offline sessions
+- Test online/offline transitions
