// Proxmox API Simulator — CI/CD: multi-arch push (Harbor + Docker Hub) + deploy
//
// Один файл: Build (DinD) → Deploy (kubectl set image в релиз simulators).
// Первый install lab — через DevOpsTools/K3S: make addon-simulators
// (Ingress https://proxmox.devops.org.ru уже из addon values).
//
// Версия образа = VERSION из коммита. Локальный bump: make bump-patch / make push.
// Теги: :{VERSION} и :latest (без sha).
//
// Credentials (Global):
//   harbor-devops-tools-push-pull-access — Harbor devops-tools (robot)
//   docker-hub                          — Docker Hub (inecs)
//   k3s-kubeconfig                      — kubeconfig к K3S
//   ssh-gitea-key                       — SCM checkout Gitea (в job)
