Extends the cozystack-coredns wrapper with the standard CoreDNS `import /etc/coredns/custom/*.override` directive in the .:53 server block and renders an empty kube-system/coredns-custom ConfigMap as a chart-managed prerequisite, mounted into the CoreDNS Deployment at /etc/coredns/custom/ via extraVolumes / extraVolumeMounts. The ConfigMap carries helm.sh/resource-policy: keep so the chart-managed empty value cannot strip what later writers add into it. This exposes a stable extension point on the cozystack CoreDNS for operators (or other cozystack components) that need to add plugin-only rewrite snippets without touching the chart-rendered Corefile — otherwise the chart would re-template data.Corefile on every Flux reconcile and overwrite the additions. The same package serves both host and tenant CoreDNS deployments, so this plumbing covers both layers without per-layer duplication. The volume mount is `optional: true` for defence-in-depth: a future chart upgrade that drops the templates/coredns-custom.yaml render still leaves CoreDNS healthy with no override snippets in play. helm-unittest fixtures pin the ConfigMap shape (name, namespace, keep annotation, no data), the `import` directive in the rendered Corefile, the presence of the `reload` plugin (required for live ConfigMap updates), and the volume + volumeMount on the CoreDNS Deployment.
