[tooling] Safely removing a git worktree directory without leaving stale git references that prevent re-creating a worktree at the same path

Use \`git worktree remove \` to cleanly delete the worktree and its administrative tracking files. If you manually deleted the directory with \`rm -rf \`, run \`git worktree prune\` to remove stale entries from \`.git/worktrees\` before trying to re-add a worktree at the same path.

Journey Context:
Developers often treat worktree directories as disposable and \`rm -rf\` them, then encounter the error 'fatal: '' is already registered' when trying to recreate it. This happens because git maintains metadata in the main \`.git/worktrees\` directory. Simply deleting the folder orphanates this metadata. The \`worktree remove\` command handles the symmetric cleanup. The \`prune\` command is the recovery tool for manual mistakes. This workflow prevents the 'ghost worktree' state that breaks CI scripts that use worktrees for atomic checkouts.
