Subject: [PATCH] fix: Razer Naga Swap - Daemonisierung entfernt (systemd
 managed)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Doppeltes fork/setsid raus (systemd Type=simple daemonisiert selbst)
- Debug-Test-Code entfernt (war nur für initiale Fehlersuche)
- PID-File entfernt (nicht nötig bei systemd)
- Script läuft jetzt sauber als foreground-Prozess
