chore: Start ESM conversion - Phase 1

Convert core library files to ES modules:
- Add 'type': 'module' to package.json
- Convert lib/codecept.js: import statements, export default
- Convert lib/event.js: export default
- Convert lib/output.js: import statements, export default
- Convert lib/utils.js: import statements, export named exports
- Convert lib/utils/mask_data.js: export named exports

Changes:
- Replace require() with import
- Replace module.exports with export/export default
- Add .js extensions to local imports
- Add __filename/__dirname polyfills using import.meta.url

Note: TypeScript errors are expected and will be resolved in later phases.
Next: Convert helper files, container, workers, and test files.
