Run Github Copilot App in Browser like vscode-web

### Feature summary

_No response_

### What problem are you trying to solve?

Thousands of customers use [DevPods](https://devpod.sh/) which are accessable only over webversion of vscode or over ssh. Bringing Devs and none devs back to their Desktop to do dev does not make sense.

The Github Copilot app should provide a webversion like [vscode webversion](https://code.visualstudio.com/docs/remote/vscode-web) which allows to work on the DevPod with multiple sessions and multi repositories.
This approach allows to have a clear and secure DevPod boundary, and no need to harden the Github Copilot app for windows setups.

### Proposed solution

Provide Github Copilot App as webserver version to be deployed on remote host, so that it can be used in standardized development environments like DevPods.

El issue no menciona archivos del repositorio, pruebas ni puntos de entrada. Empieza revisando las referencias enlazadas de VS Code Web y DevPod para entender el flujo de trabajo solicitado para el host remoto. La tarea estaría terminada cuando exista una ruta definida de despliegue en un servidor web para la aplicación Copilot, con varias sesiones y compatibilidad con múltiples repositorios.
