Represents a k3s Kubernetes cluster running as a privileged container resource. Injects the cluster's kubeconfig into a dependent resource.

- Host processes receive `KUBECONFIG=<host-path>/local/kubeconfig.yaml`.
- Containers receive `KUBECONFIG=/tmp/k3s-kubeconfig.yaml` and a file-level bind-mount of the container-network kubeconfig variant. Both are applied by the `BeforeStartEvent` subscriber registered in `AddK3sCluster`.
