#   1. Docker (default): Full core_nest structure + source code
#   2. Bare metal (--bare-metal): Only pawprint source to systemd services
#
# Usage:
#   ./deploy.sh                  # Deploy Docker setup (default)
#   ./deploy.sh --bare-metal     # Deploy bare metal pawprint only
#   ./deploy.sh --dry-run        # Preview what would be synced
#   ./deploy.sh --bare-metal --dry-run  # Preview bare metal sync
