The only thing I'm not sure about are the tests. If you look at uv's example library project structure:

example-lib
├── .python-version
├── README.md
├── pyproject.toml
└── src
    └── example_lib
        ├── py.typed
        └── __init__.py

...it's not really clear where a tests module should go. Maybe in src?

@r-thomson, Test in the root directory follows https://github.com/pypa/sampleproject, IMO we should keep the proposed structure, but I don't think it matters that much.

Look sweet. We should cut a minor release to test our deploy after this gets merged.
