This pull request fixes #5817.

The issue has been successfully resolved. The AI implemented a complete solution that directly addresses the core problem where the frontend incorrectly showed "agent has stopped" when the websocket disconnected.

Key changes made:

1. Added a proper DISCONNECTED state to handle websocket disconnections
2. Implemented appropriate UI feedback with "Disconnected, trying to reconnect..." message
3. Added visual indication (orange warning state) to show connection issues
4. Fixed the state management to properly track disconnected vs stopped states
5. Added test coverage to verify the behavior

The solution is comprehensive as it:

• Fixes the incorrect status message
• Provides clear user feedback about connection state
• Maintains accurate state tracking
• Includes proper internationalization support
• Has test coverage to prevent regression

This can be confidently sent to review as it addresses all aspects of the original issue while maintaining good software engineering practices (testing, i18n, proper state management).
