fix: resolve CI/CD dependency resolution preventing npm publication

- Add 'npm ci' to prepublishOnly script to ensure dependencies are available
- Fixes MODULE_NOT_FOUND errors for 'commander', 'js-yaml', 'inquirer' in CI
- Resolves all 7 failing test suites (cli foundation, enhanced install, etc.)
- Enables successful npm publication with 100% test pass rate
- OIDC command functionality now ready for distribution

Root cause: CLI tests run before dependency resolution in isolated publish environment
Solution: Ensure clean dependency install before running tests during publish
