Since the uv.lock is a toml file, maybe it should be commentable.

In addition to uv.lock file there is also the .python-version file. Maybe they should be added together.

Sounds reasonable to me. Would you mind adding the other file and fixing the tests? Otherwise, if this is marked as ready, I would merge.

Thanks @perillo

I will merge this as-is. It's a generated file, so comments written into the file might be overwritten.
