Feature request: I want to control Copilot activity on multiple owned machines from the same GitHub Copilot app instance

Feature request: I want to control Copilot activity on multiple owned machines from the same GitHub Copilot app instance.

The main motivation is simply that Copilot requires lots of compute resources to do its work. Well, I have many machines - I can run sessions on each of them concurrently. Today, this requires cumbersome orchestration to actually operate Copilot from each machine locally. The remote steering does not cut it - I want the ability to fully operate each local Copilot (start new sessions etc).

This is also an obvious stepping stone to coordinated Copilot sessions, where a supervisor session on one PC can of its own accord spawn concurrent sessions across a distributed set of Copilot enabled machines connected to my app, so is likely a valuable feature strategically for future expansion of functionality.

There are many ways this could be done but something as simple as a "allow remote control" checkbox on the "server" side + "enter IP+port" on the "client" side would be perfectly fine to satisfy my needs (e.g. with the auth being based on me being logged in on both sides with the same user).

首先，检查 GitHub Copilot 应用当前如何运行本地会话并提供远程控制。定义多台自有机器如何连接和进行身份验证，然后确定用户如何在每台机器上启动和控制会话。完成标准是：一个应用实例能够完整运行跨已连接机器的并发会话。
