Could Copilot support a hook or command that runs after it creates a project worktree?

My app needs an ignored `.env.local` file. I use a Git `post-checkout` hook to symlink it from the main checkout, but that hook does not run for Copilot-created worktrees. As a result, I have to set it up manually before I can run the app.

A simple per-project “run this after creating a worktree” setting would solve this and support other local setup needs too.

Start by tracing how the app creates Copilot project worktrees and how project-specific settings are loaded. Define where a per-project post-creation command would be configured and invoked, including the existing Git worktree setup case. Done means a configured command runs after creation and supports local setup such as linking .env.local without requiring manual intervention.
