uv appears to be working with 3.13t

I noticed in this post: actions/setup-python#771 (comment)

Yes, uv python install 3.13t supports it (specifically python-build-standalone added it, which is what hatch, pdm, etc use too, and then uv added support for requesting it). uv itself has supported it since something like March.

Thanks for confirming @henryiii

I think I'm sold on wholesale switching to it. See numpy/numpy#27581 for part of the work to do this for NumPy.

@ngoldbaum I've been using uv pretty extensively in all my project and have had great success with it. It seems others in the community are having similarly positive experiences with it, too.

Side note, one of the things I've been LOVING about uv is that it supports editable local packages sources (e.g. local git submodules or vendored/copied package sources, which I sometimes prefer over git+https:// remote package sources)

# pyproject.toml
[project]
dependencies = [
  "my-package-source",  # see below for local source code location.
]

[tool.uv.sources]
# this is like `cd submodules/my-package-source && pip install -e .`
my-package-source = { path = "submodules/my-package-source", editable = true }

I'm a little less enthusiastic about uv as a setup-python replacement today: numpy/numpy#27581 (comment)

But I think we can still suggest it so people can install free-threaded Python on CI in a uniform way.
