Tyler King 9dc5cb9eee feat: Kubernetes native integration — Helm chart + K8s/SPIFFE config
Helm chart (charts/bascule/):
  Deployment with shell sidecar container (shared jumphost model)
  Service (LoadBalancer/NodePort/ClusterIP)
  ConfigMap with auto-generated config.toml
  RBAC (Role + RoleBinding for pods/exec)
  NetworkPolicy (restrict shell egress, allow DNS + K8s API)
  ServiceAccount with create flag
  Configurable shell image (k8s-ops, net-ops, dev, minimal)
  Helm lint passes clean

K8s backend config (bascule-core):
  [k8s] section: enabled, namespace, pod_name, shell_container, shell
  Auto-detection via POD_NAME/POD_NAMESPACE env vars (downward API)
  Backend priority: K8s > proxy > container > local PTY
  K8s exec implementation deferred to --features k8s (kube crate)

SPIFFE/SPIRE auth config:
  [auth.spiffe] section: trust_domain, trust_bundle_path, workload_api_socket
  JWT-SVID token-as-password authentication pattern
  Implementation deferred to bascule-auth-spiffe crate

Zero substrate dependencies. Default build unchanged.
