Migrate from ESLint to oxlint for 50x performance improvement (#9682)

* Migrate from ESLint to oxlint - Upgraded ESLint to v9 and created flat config for migration compatibility - Used @oxlint/migrate tool to generate .oxlintrc.json configuration - Installed oxlint v1.7.0 for 50-100x performance improvement - Updated package.json scripts to use oxlint instead of eslint - Updated lint-staged configuration for pre-commit hooks - Configured ignore patterns for migrations, scripts, and build files - Removed old ESLint dependencies and configuration files - Maintained equivalent linting behavior with much faster execution Performance improvement: ~17 seconds → ~350ms (48x faster) * rules * --prefer-offline to speed up yarn install --------- Co-authored-by: codegen-sh[bot] <131295404+codegen-sh[bot]@users.noreply.github.com> Co-authored-by: Tom Moor <tom@getoutline.com>
