feat(service): add sync-restart convenience command

Add make sync-restart for easy updates:
- Auto-detects systemd service vs tmux-based installation
- Pulls latest code via make sync
- Restarts services appropriately
- Works for both native and ARK-OS installations

Usage:
  make sync-restart
  bash scripts/service/sync_and_restart.sh
