隧道/端口转发可以参考mobaxtrem软件，独立出来不用单独打开session

独立一个入口/面板，这样就不用去会话里面找隧道相关的设置。一次配置打开windterm软件，隧道功能就打开了

Start by reviewing how tunnel and port-forwarding settings are currently exposed inside a session. Compare that flow with the requested standalone panel and determine how one-time configuration should enable the tunnel when WindTerm opens. Done means users can configure and access tunneling without opening a session, with the behavior matching the requested example.
