* refactor: switch operator from CRD to ConfigMap
Replace the WindmillInstance CRD with a plain ConfigMap for the K8s
operator. This simplifies deployment (no CRD to install/manage, no
ClusterRole for custom API groups) while keeping the same config schema.
- Replace crd_ee.rs with configmap_ee.rs (parses data.spec YAML key)
- Rewrite reconciler_ee.rs: ConfigMap watcher + Event recorder instead
of CRD Controller + status subresource
- Add license_key preservation: if absent/empty in ConfigMap but present
in DB, the DB value is kept
- Remove print_crd_yaml() and "operator crd" subcommand
- Drop schemars, chrono, instance_config_schema dependencies
- Delete manifests/crd.yaml
- Update K8s example and README for ConfigMap approach
- RBAC now only needs a namespace-scoped Role (not ClusterRole)
