Switch from biome to oxc

[martpie]

I don't know if I'll move forward with this, I'm just playing with it. There are things I like, things I don't.

Overall, Biome opinions feel nicer, everything make sense. On the other hand, oxc may have momentum (as it come from the creators of vite), so better integration with vitest, etc.

Pull request overview

This PR experiments with replacing Biome-based lint/format tooling with the Oxc toolchain (oxlint + oxfmt), and updates CI and code formatting to match the new tooling output.

Changes:

• Replace Biome with oxlint/oxfmt in npm scripts and add corresponding config files.
• Update GitHub Actions workflow to run separate format + lint steps (and adjust YAML formatting).
• Apply mechanical formatting changes across TS/TSX/HTML/Markdown and update translation source references accordingly.

package.json:84

• oxfmt/oxlint packages in the lockfile require Node ^20.19.0 || >=22.12.0, but package.json doesn’t declare an engines.node constraint. Adding an explicit Node engine (and/or an .nvmrc) would prevent confusing install failures for contributors on older Node versions.
