The estate direction is all-in-kubernetes, so pdbmux (a long-running daemon)
should run as an in-cluster service rather than an RPM-installed systemd unit
on each VM. The RPM is for workstation/VM CLI tools only; a daemon does not
belong there.
- Remove packaging/pdbmux.service and drop pdbmux (binary, systemd unit,
completions) from the RPM/nfpm spec and build-rpm.sh.
- Keep pdbmux in the Makefile build and the test suite.
- Add Dockerfile.pdbmux building a static CGO_ENABLED=0 binary on distroless
(mirrors encapi's image style).
- Add .woodpecker/docker.yaml to build+push git.unkin.net/unkin/pdbmux:<tag>
on v* tags via the docker-buildx plugin (droneci/DRONECI_PASSWORD creds,
same as encapi), with k8s resources set.
- Update README/AGENTS.md: deployment is k8s, config via PDBMUX_* env.
