Add scripts to extract OpenAPI v3 schemas from CRD definitions in all
kustomize overlays and write JSON schema files to ci/crd-schemas/ for
kubeconform validation. This allows kubeconform to validate CRD instances
(Elasticsearch, Kibana, CNPG Cluster, VictoriaMetrics, etc.) instead of
skipping or erroring on them.
- ci/generate-crd-schemas.py: extracts schemas from CRD YAML on stdin
- ci/generate-crd-schemas.sh: iterates overlays, pipes to Python script
- ci/validate-apps.sh, ci/validate-clusters.sh: add local schema-location fallback
- Makefile: add generate-schemas target
- ci/crd-schemas/: 67 generated schemas (cert-manager, cnpg, elastic, victoriametrics, argocd, gateway)
- .pre-commit-config.yaml: raise large-file limit to 2 MB for generated schemas
Run `make generate-schemas` to regenerate after CRD version changes.
