// Wrapped — CI: auto SemVer bump + multi-arch push (Harbor + Docker Hub) + deploy
//
// Триггер: push в main (webhook Gitea → Jenkins Multibranch).
// Коммиты с [skip ci] в сообщении — без повторного bump (анти-цикл после version commit).
//
// Credentials:
//   harbor-devops-tools-push-pull-access — Harbor devops-tools
//   docker-hub                          — Docker Hub
//   gitea-ssh (или GIT_SSH_CREDENTIALS_ID) — SSH для push bump-коммита
//
// Версия: файл VERSION (+ pyproject / Helm). Теги образа: :<semver>, :<sha>, :latest
// Deploy: devops-tools/wrapped/wrapped-deploy/main
