Upstream has now published on crates.io all of the forks they depended on.
For the entire `uv` workspace, there are currently about 20 dependencies missing, but if we focus on uv-build, only astral-version-ranges and spdx seem to be needed. I'm working on both.
It might make sense to make a first upload of uv without providing all of the crates in the workspace and iterate from there. Manuel, in which form do you need `uv-build`? Just as a binary package exposing the `uv_build` binary, I assume?
