Refactors K8sDeployer.up() into three composable methods:
- _setup_cluster_and_namespace(): kind cluster, API, namespace, ingress
- _create_infrastructure(): PVs, PVCs, ConfigMaps, Services, NodePorts
- _create_deployment(): Deployment resource (pods)
`prepare` calls the first two only — creates all cluster infrastructure
without starting pods. This eliminates the scale-to-0 workaround where
operators had to run `deployment start` then immediately scale down.
Usage: laconic-so deployment --dir <dir> prepare
