Request: Local Sandbox support or dev container.

Request: Local Sandbox support or dev container.

I am not able to use this with sensitive data because there is a risk that prompt injection could exfiltrate the data. I would like to be able to turn off network egress for local containers so that I can restrict what commands get run.

As I can normally with the normal GH copilot CLI: https://docs.github.com/en/copilot/how-tos/cloud-and-local-sandboxes/configuring-local-sandbox-settings

Even better would be if I could bring my own container with my configuration to this.

Start by reviewing the linked GitHub Copilot local sandbox settings documentation and the app's existing container or sandbox entry points, which the issue does not identify. Clarify whether the goal is disabled network egress, support for a user-provided container, or both; done should include a documented, usable local configuration for the selected scope.
