What why should we migrate to biome? Is there something it does that eslint doesn't maybe?

[lolbinarycat]

I'm still not 100% sold on migration, as biome is significantly younger as a project, which does come with stability concerns.

however, there are many potential advantages:

1. merging of formatter and linter into a single tool, reducing the number of external deps to manage
2. dogfooding, using tools written in rust to develop rust tools, this can potentially lead to more communication between the teams, potentially improving both biome and rust
3. performance
4. i believe biome has a number of lints that eslint lacks (although the inverse is likely also true)

We're going to want to do some form of migration if we stick with eslint or not, which does offset some of the switching costs.

I think it's good to analyze both options.

This draft is mostly here for reference, since I already did this work to figure out how hard it would be.
