Kubernetes Operator Scaffolder

Provide the following inputs:

Example invocation:

> Scaffold a Go operator for a PostgresCluster resource in the db.example.com group. Spec fields: replicas (int, default 3), version (string, default "16"), storageSize (string, default "10Gi"). On create, it should provision a StatefulSet with PVCs. On delete, clean up PVCs.

Before scaffolding, the agent checks for:

# Go operator (kubebuilder path)
go version            # Go 1.22+
kubebuilder version   # kubebuilder 4.x
controller-gen --version
kustomize version
Python operator (kopf path)
python3 --version     # 3.11+
pip show kopf         # kopf framework
pip show kubernetes    # k8s client

If tools are missing, the agent provides install commands before proceeding.
