# install-macmini-autopush.sh
# Einmal-Installation des LaunchAgents für macmini-tunnel-autopush am Mac mini M4.
#
# Mac mini M4 läuft LM Studio (Port 1234), NICHT Ollama.
#
# Lädt Tunnel-Script, legt LaunchAgent an (autostart bei Login + Reboot, KeepAlive).
# Räumt vorhandene Ollama-Quick-Tunnel/Konflikte auf.
#
# Verwendung am Mac mini:
#   curl -fsSL https://files.raumkommander.at/install-macmini-autopush.sh | bash
#
# Mit fixer Named-Tunnel-URL (empfohlen, einmal cloudflared tunnel login vorher):
#   curl -fsSL https://files.raumkommander.at/install-macmini-autopush.sh | \
#     CF_NAMED_TUNNEL=macmini-raumkommander \
#     CF_NAMED_HOSTNAME=macmini.raumkommander.at \
#     bash
#
# Mit abweichendem LM Studio Port:
#   curl -fsSL https://files.raumkommander.at/install-macmini-autopush.sh | LMSTUDIO_PORT=1235 bash
