Implements a Kubernetes operator that manages fleets of BIND9 servers declaratively, using controller-runtime (matching forgebot conventions). - add BindCluster reconciler: StatefulSet (pod-0 primary, secondaries), headless + client Services, rendered named.conf ConfigMap, TSIG keys Secret and rndc control Secret; watches dependent CRs to re-render - add BindTSIGKey reconciler that generates key material into a Secret - add BindZone/DNSRecord reconcilers using fully-dynamic delivery (rndc addzone + TSIG nsupdate against the primary pod) - add BindCatalogZone reconciler so secondaries auto-provision zones - add BindPolicy (RPZ), BindDNSSECPolicy, BindView, BindACL reconcilers - render primary/secondary named.conf variants selected by pod ordinal - generate CRDs, deepcopy and RBAC; add samples mapping the three Puppet roles (authoritative/resolver/external-dns) to three BindClusters - add Makefile, Dockerfile.operator, Woodpecker CI and kind manifests
