# CI/CD 一体化流水线（no-push 本地构建部署）
# 设计文档：docs/superpowers/specs/2026-07-08-cicd-no-push-local-build-design.md
#
# 流程：
#   PR 触发：仅跑 3 个 quality job（并行）
#   push main 触发：quality job 全绿后跑 deploy job（本地 build + compose up）
#   workflow_dispatch：支持指定 commit_sha 回滚
#
# 不依赖任何自建镜像，全部使用官方镜像
# 不推送镜像到 registry，构建即部署
