Replace the ISC dhcpd PXE-boot VM with a Kea DHCP Kubernetes operator, modelled on bind-operator. The operator renders kea-dhcp4 config from CRs and runs an HA pair of kea-dhcp4 + kea-ctrl-agent servers behind an anycast Service. - add KeaCluster/KeaSubnet/KeaClientClass/KeaAPI CRDs (group kea.unkin.net) - render deterministic kea-dhcp4.conf + kea-ctrl-agent.conf into a ConfigMap and roll the StatefulSet via a config-hash annotation; best-effort hot-reload via the kea-ctrl-agent REST channel - run HA hot-standby (memfile leases) with stable per-peer DNS identity from a StatefulSet; expose an anycast LoadBalancer Service for PureLB - represent the full legacy dhcpd config: 198.18.13-17.0/24 pools, pool-less 198.18.25.0/24, and the Legacy/UEFI-64 PXE arch classes (option 93) - add the KeaAPI-spawned REST service: Terraform-friendly CRUD over subnet and client-class CRs (stable IDs, PUT upsert, 404 drift, bearer-token auth) - add Makefile (patch/minor/major tag targets), distroless operator/api images, an AlmaLinux+EPEL kea workload image, and woodpecker CI with k8s resources + serviceAccountName on every step - unit tests for config rendering, controller reconcile/config-hash, and the API Claude-Session: https://claude.ai/code/session_01JUoARVdmhxKQHyyyp1pxeT
