build(lint): switch over to ruff; add taplo

[yajo]

Ruff is faster, better integrated, easier to configure... Cool!

Taplo also helps with toml maintenance.

There's some Nix error, but I still don't know enough about Nix to say what's wrong. 🫣

And I wonder whether the Ruff pre-commit hook also checks/applies formatting because the hook spec looks a bit outdated. With a recent Ruff version, it's ruff check for linting and ruff format for formatting. We'd want to make sure the formatting is also checked through CI. Do you know, @yajo?

I see taplo in nix's configs, but nowhere else: what does it do? I guess it's used to format TOML files in VSCode? 🤔

[yajo]

Well, nix configs make the .pre-commit-config.yaml nix-generated file use taplo. It's just a TOML formatter.

You have a brief explanation of how it works here.
