Summary

WebChat dashboard becomes unresponsive after any tool call; WebSocket disconnects and does not auto-reconnect, requiring page refresh to see results.

Steps to reproduce

1. Open Control UI dashboard at http://127.0.0.1:18789/
2. Send a message to the agent
3. Agent responds and calls a tool (e.g., session_status, exec, gateway config.get)
4. Dashboard freezes — no new messages appear
5. Close dashboard tab and reopen — all messages appear (agent was responding all along)

Expected behavior

Dashboard should remain responsive during tool calls and display results as they arrive via WebSocket.

Actual behavior

Dashboard becomes completely unresponsive. WebSocket connection drops (TIME_WAIT state observed on port 18789) and does not auto-reconnect. User must close and reopen dashboard to see results. Dashboard shows "网络聊天失败" (network chat failed) error.
