Overall it looks good and it's a pretty good addition.

I left a minor comment and another one regarding my concerning on relying on another action for what it seems just python package management.

As this is a public repo, this could be removed ?

I like the idea of having a zizmor job, however, I'm wondering if there's another simpler/safer way to run it, instead of bringing this new action (setup-uv) AFAICT just for the python package manager 🤔
