Move the running stack off root ownership. The systemd service now runs as User=clawmates:clawmates with WorkingDirectory=/opt/clawmates, and the script's COMPOSE_DIR default follows. This closes the "rootful compose stack" ask from the original ship-readiness audit — deploys no longer require any part of the pipeline to run as root beyond docker access (the clawmates user gets that via the docker group). Docker-managed volumes (pgdata, broker_run, broker_key, brains, filedata) stay put; the compose project name is unchanged so docker resolves them to the same physical volumes. The old /root/clawmates directory stays in place as an emergency rollback for a week, then gets removed as follow-up.
