voice-agent/mac-worker/deploy/install-launchagent.sh

#!/usr/bin/env bash
# Voice-Agent Mac-Worker — vollständiger Installer.
#
# Macht alles, was nötig ist, damit der Worker dauerhaft läuft:
#   - Python-venv anlegen + Dependencies installieren (idempotent)
#   - .env aus Vorlage anlegen (falls fehlt)
#   - LaunchAgent registrieren / aktualisieren / starten
#   - Health-Check
#
# Kann beliebig oft erneut laufen (z. B. nach git pull).
#
# Befehle:
#   ./install-launchagent.sh            # installieren / aktualisieren
#   ./install-launchagent.sh uninstall  # entfernen
#   ./install-launchagent.sh status     # Status + letzte Logs
#   ./install-launchagent.sh restart    # Worker neu starten (kein Reinstall)
