fix: graceful exit with proper terminal cleanup

- Use renderer.destroy() instead of stop() for proper terminal state restoration
- Let OpenTUI handle Ctrl+C via built-in exitOnCtrlC
- Add onDestroy callback to ensure process exits after cleanup
- Fixes cursor visibility and terminal state issues on exit
