Subject: [PATCH] ci: build weave-kube and weave-npc, push to this Gitea's
 registry

A Gitea Actions workflow that builds the two images the cluster runs from
reweave/build/Dockerfile (linux/amd64 only) and pushes them to
git.levk.dev/reweave/{weave-kube,weave-npc}, tagged with the full commit
SHA so a tag never changes meaning. It stops at the push; rollout is the
CD side's job. Build-time fetches (base images, apt/apk, Go modules) stay
external for now and are to be peeled out once self-deploy works.
