feat: optimize Node.js installation in CLI workflow

NODE.JS OPTIMIZATION: Use existing installation and improve version management

Improvements:
✅ Node.js 24: Uses existing installation (24.13.0) - skips reinstall
✅ Node.js 20: Installs LTS version for stability testing
✅ Version-specific logic: Different handling for each version
✅ Better logging: Clear version information and actions

Benefits:
- Faster execution for Node.js 24 job (no reinstall needed)
- Proper LTS stability testing with Node.js 20
- Clear visibility of which version is being used
- Reduced network requests and installation time

Rationale:
- gitea-runner already has Node.js 24.13.0 installed
- Node.js 20 LTS is available via apt repos for stability testing
- No need to reinstall Node.js 24 on every workflow run
- Optimized for the actual production environment

This makes CLI testing faster and more efficient while maintaining
both current version testing (24) and LTS stability testing (20).
