fix: clean up empty parent directories after pruning worktrees#137
Conversation
When pruning a worktree for a branch with slashes (e.g., feature/my-branch), only the leaf directory was removed, leaving empty parent directories behind. Now walks up the directory tree after removal, deleting each empty ancestor until reaching the project root or a non-empty directory. Replaces the multi-remote-only `cleanup_empty_remote_dir` with a general `cleanup_empty_parent_dirs` that works unconditionally for all worktrees.
