- Added WebSocket endpoint for real-time chat interactions.
- Refactored ChatPage component to utilize WebSocket for sending and receiving messages.
- Updated chat service to handle streaming responses from the LLM agent.
- Introduced error handling for WebSocket connections and message processing.
- Modified Editor_Test to include AppShellWithMenu for better layout.
- Adjusted file path in generar_tree.py for correct directory structure.
- Created llm_chat_endpoint_v1.py and llm_chat_srvc.py for handling chat requests and responses.
- Established logging for WebSocket interactions and errors.
