Add a few dotfiles to improve newcomers' experience

WDYT about Astral’s tools, Ruff and uv?

I don't have anything against uv a priori although last time I tried it installing PyTorch was a headache. We would need to make sure everything works out of the box on every supported platform, and document the decision if we were to go this route.

Yeah, my concern is, iiuc, that for now, we distribute the library without any kind of lock file. I will advocate for at least adding an uv.lock (or similar) to ensure the ability to reproduce a developer environment. Also, if I end up adding support for Nix, I would likely use uv2nix.

Let's open a discussion to weigh pros and cons of uv. ruff is raising some interesting style issues already, I'm not opposed to using it.

Overall this looks good to me, and before fixing the code style check I want to understand why ruff asks for explicit re-exports here before merging. An issue on the ruff repository refers to PEP484 but I am still not sure how this is related.

I’ve read a bit about this online, but I’m not sure to have any strong opinion. That said, it seems like ignoring certain lints (as vllm does) while fixing others is a reasonable strategy, WDYT about ignoring E731 and F401 but addressing E721?

LGTM and ruff lints to ignore seems reasonable 👍
