Executor was the only control-plane container running as root (uid=0),
writing root-owned files to /opt/homelab via bind-mount and triggering
false sudo on every deploy.
- Dockerfile: add USER homelab after useradd (useradd already present)
- docker-compose.yml: add user: "1000:1000" and group_add: ["999"]
(GID 999 = docker group on VPS) so executor retains docker.sock access
