- Migrate from CommonJS require/module.exports to ES import/export syntax
- Update package.json to use "type": "module" and require Node.js >=18
- Add Babel configuration for Jest testing with ES modules
- Update GitHub Actions workflow to test Node.js 18, 20, 22
- Modernize Node.js imports to use node: protocol
- Update version to 2.0.0 reflecting breaking changes
