Subject: [PATCH] test: add Jest configuration and fix test path resolution

- Add jest.config.js with proper Node.js environment configuration
- Fix train.test.js to use correct relative path: '../../js/train.js'
- Add module.exports to train.js for Node.js module loading
- Update package.json with proper test scripts (test:unit, test:e2e, test:coverage)
