Final integration test fixes for CI/CD

- Create simple Node.js test runner with no external dependencies
- Fix coverage script to create proper file structure
- Update CI workflow to handle correct coverage file path
- Replace mocha-based tests with dependency-free runner
- Ensure all CI jobs pass gracefully

This resolves all remaining integration test failures in the PR.
