### Migration Guide

If you're upgrading from v1.x:

1. **Update to ESLint v9**:

   ```bash
   npm install eslint@^9.0.0 @typescript-eslint/eslint-plugin@^8.29.1 @typescript-eslint/parser@^8.29.1 @stylistic/eslint-plugin@^2.13.0 @eslint/js@^9.0.0
   ```

2. **Migrate to flat config**:

   ```javascript
   // Old (.eslintrc.js) - NO LONGER SUPPORTED
   module.exports = {
     extends: ["ts-strict"],
   };

   // New (eslint.config.js) - REQUIRED
   import tsStrict from "eslint-config-ts-strict";
   export default [...tsStrict];
   ```

3. **Remove `.eslintrc.*` files** and create `eslint.config.js`

4. **Update Node.js** to version 18.18.0 or higher

⚠️ **Note**: This version does NOT support ESLint v8 or legacy configuration formats. If you need ESLint v8 support, continue using v1.x of this package.
