- Add ESLint 9 flat config (eslint.config.mjs) with typescript-eslint recommended rules and eslint-config-prettier - Add lint-staged to run eslint+prettier only on staged files - Update pre-commit hook to use lint-staged instead of full prettier check - Add `lint` and `format:check` scripts to package.json - Add Lint step to CI workflow - Fix resulting lint errors: unused vars (_ctx, _options, catch binding), any→unknown in type declarations, stale eslint-disable comments Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
