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.

首先追踪应用如何创建 Copilot 项目 worktree，以及如何加载项目特定的设置。确定应在哪里配置和调用每个项目的创建后命令，包括现有的 Git worktree 设置场景。完成的标准是：已配置的命令会在创建后运行，并支持本地设置（例如链接 .env.local），无需手动干预。
