Code formatting comes to uv experimentally

I'd rather `ruff` being merged with `ty` instead. `uv` for me is about package / project manager. It's not about code style. The only time `uv` should edit a code file is to update its dependencies (PEP 723).

On the other hand, both `ruff` and `ty` are about code style. They both edit the code, either to format or fix typing / lint issues. They are good candidates to be merged.

I think the goal is to make uv a complete package manager for Python while still giving you the option to use the parts separately.

uv is like cargo for python.

If you only need a fast type checker you can just use ty, if you just need a fast formatter and linter you can just use ruff.

Combining ruff and ty doesn't make sense if you think about like this.

Including a formatter in a package manager doesn't make sense to me. Seems like obvious feature creep.

My understanding was that uv is for installing dependencies (e.g. like pip) with the added benefit of also installing/managing python interpreters (which can be reasonably thought of as a dependency). This makes sense. Adding more stuff doesn't make sense.
