- Set "type": "module" in package.json to enable ESM throughout the project.
- Changed "main" in package.json to "dist/index.js" to point to the bundled output generated by ncc.
- Updated Jest configuration (jest.config.js) to ESM format and to use babel-jest for TypeScript transformation.
- Added/updated babel.config.js in ESM format to support TypeScript and ESM for Jest.
