## Summary This is causing some cyclic dependencies issues for me, because these can be used in virtually _any_ crate (like `uv-install-wheel`), which then means that all of `uv-configuration` becomes a dependency, etc. I think this should be a leaf crate so that we can safely depend on it anywhere.
