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.
