soul-demo now runs as a k3s Deployment with HPA (1–8 replicas, 60% CPU target) instead of a bare background process. k3s starts first in entrypoint.sh, imports the soul-demo:local OCI tar from /var/lib/rancher/k3s/agent/images, and auto-applies the Deployment, NodePort Service, and HPA from the server/manifests dir. neuron-web starts only after the soul-demo pod is Running. Cloud Run gen2 execution environment required for k3s (provides /dev/kmsg and Linux capabilities).
