Code formatting comes to uv experimentally

This is obviously a great move. I don't know why so many commenters here are against making things better. "Can't you just do <this slightly worse thing> already?". Well yes. But it's slightly worse.

I think the biggest thing is that it doesn't seem to support other formatters. If my project uses black I don't get to have uv format work for me.

Ruff pretty much follows the same rules as black, and can be made identical with some options tweaking.

So when I moved several projects from black to ruff, there were no changes made to the code.

I find this hard to believe since black doesn't even have the same rules as black's next version and I never changed version without something being reformatted.

Also because of fun, if you reformat again with the older version it won't go back to as it was before :)
