Expected behavior
Extension should connect to the local daemon automatically, showing "已连接 / READY".

Actual behavior
Extension shows "未连接" (disconnected). Browser console shows:
WebSocket connection to 'ws://127.0.0.1:52800/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

Additional investigation
bsk status reports daemon is running with ws_port: 52800.
However, netstat -ano | findstr 52800 shows no process listening on port 52800.
bsk daemon start (default auto-detach mode) starts a daemon process, but the process exits shortly after.
bsk daemon start --foreground keeps the daemon alive, and the extension connects successfully.
This suggests the Windows auto-detach mechanism is not working properly.

Workaround
Run daemon in foreground and keep the terminal window open:
bsk daemon start --foreground
Or create a desktop .bat file with the same command.
