Backend fixes:
- Fix server crash when logging large session_state messages (186 agents)
- Use safe logging that extracts only message/stack properties
- Prevents TypeError in util.inspect on circular refs or deep objects
Frontend loading state fixes:
- Add reactive WebSocket update to prevent stale session.ws references
- Add timeout/retry wrapper for session_state loading (3 retries × 15s)
- Add hasEverReceivedSessionState flag to track cached data across reconnects
- Implement data-aware loading (isInitialLoad vs isRevalidating)
- Show reconnecting badge instead of hiding agents on reconnect
Debug improvements:
- Add detailed connection state logging in useAggregatedAgents
- Add connection status logging in AgentInputArea
- Track connecting reasons for easier debugging
Fixes:
- Agent screen no longer shows false "Offline" toast on reconnect
- Home screen shows loading immediately (no empty state flash)
- Home screen keeps agents visible during reconnect with badge
- Stuck loading has timeout protection with graceful degradation
- Server no longer crashes when sending session_state with many agents
