When I close the app, it looks closed, but I can see it running in the background when I open the task manager. Now, when I close the laptop, come back after some time, and try to open the app, it doesn't open. I have to click twice to open it. During this time, if my Azure Remote MCP is disconnected, the mcp servers list shows it as connected, but it's not working.

在 Windows 10.0.26200 上使用应用版本 1.1.10 重现该行为，从 /chat 路径开始，并测试应用关闭/重新启动以及断开连接的 Azure Remote MCP。完成标准是：关闭应用后不会留下意外的后台进程，重新启动在第一次尝试时即可成功，并且断开连接的 MCP 服务器不会显示为已连接。
