Devcontainers do not work with git worktree

使用 git worktree add ../blueapi-enum add-enum-for-endpoint 重现问题，然后在其 devcontainer 中打开 worktree 并运行 uv sync。检查 devcontainer 配置以及 worktree 对 .git 的处理；当从已打开的 worktree 中执行 Git 命令和 uv sync 时，不再出现报告的 repository 或 setuptools-scm 错误，即表示完成。

Way to replicate this issue

1. In a cloned repository add a worktree by

git worktree add ../blueapi-enum add-enum-for-endpoint

You will see that inside the worktree the .git has a link to the parent and not the

gitdir: /scratch/ckk43848/blueapi/.git/worktrees/blueapi-enum

2. Open the blueapi-enum in devcontainer
   See the following issues

fatal: not a git repository: /scratch/ckk43848/blueapi/.git/worktrees/blueapi-enum

      Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout
      without the .git folder) don't contain the necessary metadata and will not work.

      For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

      Alternatively, set the version with the environment variable SETUPTOOLS_SCM_PRETEND_VERSION_FOR_${NORMALIZED_DIST_NAME} as described in
      https://setuptools-scm.readthedocs.io/en/latest/config/


hint: Build failures usually indicate a problem with the package or the build environmen

Possible solution:

Try to mount the parent as well when devcontainer knows that it is a worktree
