.lintstagedrc.mjs

// lint-staged config — moved here from package.json so we can use a
// function to filter file lists before invoking oxlint. The default glob
// picks up files under src/tests/, but oxlint excludes that directory via
// ignorePatterns in .oxlintrc.json; passing it nothing-but-ignored files
// makes oxlint exit non-zero with "No files found to lint", which breaks
// the pre-commit hook for test-only changes. The filter drops src/tests/
// paths before invoking oxlint; oxfmt still formats them.
