- main linting is now done by oxlint. eslint remains for linting json
files in the frontend (until oxlint adds support)
- move type checking to the lint step (with --type-check)
this improves performance by removing a duplicated typescript parse task
(instead of parsing for linting then again for type checking, it parses
once for both)
- add a `lint-fast` npm script to get some fast fail behavior. it simply
lints with no type information
- oxc plugins are still in preview, so the custom plugin that checks for
`__testing` usage outside of tests runs outside the main linting job
until performance is improved
- fixes some type issues (and config issues) that were not visible due
to a missing type check on some files. now type checking will run on
every file that is linted
- split up oxc config for easier management
