## Summary Instead of looking at _either_ `pyproject.toml` or `setup.py`, we should just be conservative and take the most-recent timestamp out of `pyproject.toml`, `setup.py`, and `setup.cfg`. That will help prevent staleness issues like those described in https://github.com/astral-sh/uv/issues/1913#issuecomment-1961544084.
