fix(cli/run): correct runtime banner identity and port-in-use error handling
- Display correct runtime identity as 'Vix.cpp' instead of hardcoded 'VIX'
- Ensure READY banner matches runtime output markers consistently
- Improve port already in use error detection and reporting
- Fix SIGINT handling to avoid duplicate READY output after interruption
- Clean up runtime flow to properly mark stopped vs failed states
