- Add has_systemd_support() function to detect if systemd is available - Checks for systemctl command - Verifies /run/systemd/system directory exists - Confirms PID 1 is systemd (handles Docker/GitHub Actions) - Tests communication with systemd via show-environment - Add install_systemd_service() function to create and enable service - Creates /etc/systemd/system/openplc-runtime.service - Runs daemon-reload and enables service with --now flag - Service runs start_openplc.sh as root - Update installation completion message - Shows systemctl commands when service is installed - Falls back to manual start instructions when systemd unavailable This allows native Linux installations to automatically start the runtime on boot while gracefully skipping service installation in Docker containers and GitHub Actions environments.

This pull request enhances the installation process for OpenPLC Runtime by adding robust systemd service detection and automated service installation. The script now checks for systemd support in a reliable way and, if available, installs and starts the OpenPLC Runtime as a systemd service, providing users with clear instructions and status updates.
Systemd service integration:
has_systemd_support()function to reliably detect if systemd is available and running as PID 1, including checks for systemctl presence and operational status.install_systemd_service()to create and enable aopenplc-runtime.servicesystemd unit, ensuring the runtime starts on boot and can be managed via standard systemd commands.User experience improvements:
.installedis created before starting the service for accurate state tracking.
