Generate Kubernetes Deployment manifests from Nickel configuration.

Includes:
- Pod template spec
- Resource requests/limits
- Environment variables from config
- Health checks (liveness/readiness probes)
- Replica configuration

Usage:
```bash
nickel export vapora.enterprise.ncl | \
  jinja2 templates/kubernetes/deployment.yaml.j2 > vapora-deployment.yaml
```

### `configmap.yaml.j2`

Generate Kubernetes ConfigMap for storing configuration.

Includes:
- Config file content
- Environment variables
- Metadata labels

Usage:
```bash
nickel export vapora.multiuser.ncl | \
  jinja2 templates/kubernetes/configmap.yaml.j2 > vapora-configmap.yaml
```

### `service.yaml.j2`

Generate Kubernetes Service manifests.

Includes:
- Service type (ClusterIP, LoadBalancer, etc.)
- Port mappings
- Selectors

Usage:
```bash
jinja2 templates/kubernetes/service.yaml.j2 > vapora-service.yaml
```

### `ingress.yaml.j2`

Generate Kubernetes Ingress for routing.

Includes:
- Host rules
- TLS configuration
- Backend service references
