The dependency resolution in 'poetry' was 'lowest', the default
dependency resolution in 'uv' is 'highest'. This means when we vendor,
we will vendor the newest/highest version possible of all transitive
dependencies that are universally/cross-platform compatible.
We could change from the default of 'highest', but I think this is
better. Various packages have been upgraded, and some have been
removed/replaced by others, and that's why there's various changes in
the <site>.txt files.
