      //     which creates the shared project root dir as a side effect.
      //   - The warm fast-path's single fused command runs `mkdir -p` for the
      //     workspace parent inline before `git worktree add`.
      // Folding the mkdir into materialization shaves one full SSH RTT off
      // every workspace startup, which is the dominant constant cost on the
      // warm path.
