Add proper CommonJS environment support for ESLint flat config: - Import globals package and add as dependency - Configure cjsConfig with node/commonjs globals and sourceType - Add jsCommonjsConfig for .js files using require/exports - Ignore .cjs files in package-level test configs to prevent overrides Fixes 20 ESLint errors across 6 packages caused by missing CommonJS globals (require, module, exports, __dirname, __filename) after flat config migration.
Add a script that automatically generates a JSON file listing all deprecated ESLint rules from core ESLint and all plugins used in the config. This enables tooling to programmatically identify and handle deprecated rules. The script: - Queries rule metadata from ESLint core and 12 plugins - Tracks which deprecated rules are configured in our ESLint configs - Records replacement rules when available - Supports both flat config (flat.mts) and legacy CJS configs Output is written to printed-configs/deprecated-rules.json.
