 - Staging Web 构建在拉取 docker.m.daocloud.io/library/node:20 时卡住，属于外网基础镜像依赖问题。

+- Deploy workflow 已升级为先使用本地缓存的 docker.m.daocloud.io/library/node:20 执行 
+pm ci && npm run build 生成 pps/web/dist。
+- Staging deploy 显式设置 BUILD_WEB=1 WEB_DOCKERFILE=infra/docker/web-artifact.Dockerfile，使用当前 commit 的 dist 构建 nginx artifact 镜像。
+- docker run 使用 --pull=never，避免再次因外网基础镜像拉取阻塞。
