# Forgejo Actions CI — runs on push, executed by the in-cluster runner inside
# the ci-builder job container (docker CLI + buildx + git). Fully sovereign:
# no external actions (manual git over forgejo-http), builds via the in-pod
# DinD ($DOCKER_HOST), pushes to Forgejo's registry, bumps the manifest tag
# (commit marked [skip ci]) so Argo CD redeploys.
