Subject: [PATCH] Pi5 'butler' (arm64) als AI-Orchestrator-Host aufnehmen

- pfannkuchen.ini: neue Gruppe [ai] mit butler (10.5.85.2), child in all/backup/hawser
- docker-Rolle: arch dynamisch via 'dpkg --print-architecture' statt hardcoded amd64
  (check_mode:false, damit --check auf ARM nicht leeres arch erzeugt) -> arm64-tauglich
- base-Rolle: Raspberry Pi OS erkennen (raspi.sources) -> sources.list-Ueberschreibung
  und qemu-guest-agent auf Pi ueberspringen, damit Pi-Kernel/Firmware-Repos intakt bleiben

Erster Bare-Metal-ARM-Host der Flotte. base+docker+borg+hawser+sysctl erfolgreich
ausgerollt, Docker 29.6.0 arm64 + Hawser aktiv, raspi-Repos unberuehrt.
