Git operations fail in worktree-based repositories inside container

[pythonlearner1025]

Description

When the working directory is a git worktree, the .git file contains a relative gitdir: reference to the parent repo’s .git/worktrees/<name> directory. This path does not resolve inside the container, causing all git commands to fail:

fatal: not a git repository: /Users/<user>/<project>/.git/worktrees/<worktree-name>

Repro

1. Open a project that is, or becomes, a git worktree.
2. Try any git operation from within Claude Code, such as /commit.

Expected

Git operations work normally.

Actual

All git commands fail because the gitdir path from the host does not exist inside the container filesystem.
