[Bugs] The GitHub Copilot app doesn't properly read git worktrees.

**Mood:** 😔

The GitHub Copilot app doesn't properly read git worktrees.

My folder structure works as such:
`X:/Projects/{project}` is the repo root.

Then worktrees are under the `X:/Projects/{project}/.worktrees/{worktree}` subfolders.

When I point the GHCP app to the repo root, it doesn't automatically pick up my worktrees and sessions in those worktrees.

先在 Windows 上的 GitHub Copilot 應用程式中，使用一個在 .worktrees 下包含 worktrees 的 repository 重現問題，接著追蹤應用程式如何從選取的根目錄探索 repositories 和 sessions。當開啟 repository 根目錄時能偵測到 worktrees 及其 sessions，並且在專案有合適的測試位置時涵蓋回報的資料夾配置，即表示完成。
