Chapter 3 scaffolding. Chart layout mirrors the CloudNativePG convention after reviewing the CRD-in-chart vs CRD-as-hook tradeoff: CRDs live inside templates/ (so helm upgrade re-applies schema changes) with helm.sh/resource-policy: keep so helm uninstall never deletes them. Chart publication target is hub.nationtech.io. CRD yaml is generated at chart-release time by a new `iot-operator-v0 gen-chart-crd` subcommand reading Deployment::crd() — the runtime install path remains the typed Score; only the chart deliverable uses generated yaml. Wrapped with the helm conditional + annotations by templates/crds.yaml via .Files.Get so the generated yaml stays pure. Install / upgrade / uninstall-preserves-CRD validated against a scratch k3d cluster; the operator pod naturally stays pending because the hub.nationtech.io image hasn't been published yet.
