# Auto-deploy watcher: monitors local code changes and syncs to Raspberry Pi 4
# Runs as systemd service: anthias-autodeploy
# Uses inotifywait to detect changes, debounces 5s, then rsyncs + restarts
#
# IMPORTANT: Uses include-based rsync — only syncs directories that are
# bind-mounted in docker-compose.yml. Pi-specific files (docker-compose.yml,
# staticfiles/) are NEVER touched.
