Subject: [PATCH] refactor(tests): Phase 4 - Create npm tests using
 Node.js/mocha

- Add postinstall.test.js for npm postinstall behavior (Section 10)
- Add cli.test.js for CLI argument parsing and profile handling
- Add cross-platform.test.js for cross-platform compatibility
- Tests use mocha framework with comprehensive coverage
