Description

Add proper error handling, retry logic, and user feedback for failures in the Realtime V2 implementation.

• Implement retry logic with exponential backoff for WebSocket connections
• Add circuit breaker pattern for WebSocket reconnections
• Create error boundaries in Vue components for WebSocket failures
• Implement graceful degradation strategies when agents fail
• Add proper error feedback in session error handlers (MainV2.vue:479-499)

Priority

High

References

• Code review identified basic error handling with only console logs
• No retry logic or graceful degradation currently implemented
