Dev — Build & local smoke test / build-smoke (pull_request) Failing after 2m11s
k3s fails to start in Cloud Run gen2 with "unable to select an IP from default routes" because Cloud Run's network sandbox doesn't expose a standard default route for k3s to detect. The blocking wait on k3s prevented neuron-web from ever binding port 8080, causing Cloud Run's startup probe to time out and terminate the container. Two changes: 1. Add --flannel-iface=eth0 so k3s pins to Cloud Run's eth0 rather than walking the routing table to detect a default-route interface. 2. Start neuron-web immediately after launching k3s in background. soul-demo becomes available asynchronously; neuron-web handles it being temporarily unavailable gracefully.
