Subject: [PATCH] feat(infra): in-cluster Gitea Actions runner (act_runner +
 dind)

Self-registering act_runner on node1 with a privileged docker:dind sidecar so
workflow jobs can build + push app images (k3s has containerd only, no Docker
daemon). Labels ubuntu-latest + docker; state persisted on a Longhorn PVC. The
registration token is applied out-of-band as the gitea-runner-token Secret
(not in git). Verified: runner declared successfully, dind API up.

+# Gitea Actions runner for the dezky monorepo, in-cluster on node1.
+#
+# Builds + pushes app images (platform-api / portal / booking) to the Gitea
+# container registry on push. A privileged docker:dind sidecar provides the
+# Docker daemon the runner's jobs use for `docker build`/`buildx` — k3s itself
+# only has containerd, no Docker daemon.
+#
+# The registration token is NOT in git — create the 'gitea-runner-token' Secret
+# out-of-band:
+#   kubectl -n gitea-runner create secret generic gitea-runner-token \
+#     --from-literal=token=<gitea registration token>
+# act_runner auto-registers on first start (persisted on the runner-data PVC).
