Dependency groups and uv run
— I've adopted a new (to me) pattern for my Python projects to make them easier to hack on using `uv run`. I'm using a [PEP 735 dependency group](https://peps.python.org/pep-0735/) called `dev` to declare my development dependencies - in particular `pytest` - such that running `uv run pytest` executes the tests for my project without me having to even think about setting up a virtual environment first.
