This is the first pass of ESLint on the codebase.
ESLint formatting is less strict when it comes to line-length and line-breaks then dprint/biome, so if you see formatting that you don't like... fix it! It shouldn't require a configuration change.
- This should merge clean into master (when the time comes).
- This will not merge clean into `3.9.0-DEV`, but the conflicts aren't that bad.
