chore: trigger staging deploy after PR#1585 merge

fix(ci): Web 镜像 buildx 幽灵缓存防护——Git Tree Hash Cache Bust
问题：ci-builder-persist 持久化 builder 的 buildkit 层缓存偶尔出现'幽灵命中'： COPY apps/web/ ./ 步骤认为自己没变（实际文件已改），导致 vite build 不执行，打出来的 Web 镜像前端文件是旧的。修复原理：把 apps/web/ 目录的 git tree hash 作为 build arg 传入 Dockerfile。 buildx 把 build arg 值作为缓存键的一部分，hash 变了 → RUN 步骤缓存失效 → vite build 必须重新执行。依赖层（npm ci）不受影响，仍然正常缓存。改动： 1. web.Dockerfile：新增 ARG SOURCE_HASH，在构建步骤写入 .cache_bust 文件 2. docker_build_push.sh：Web 镜像构建时计算 git tree hash 并传入 3. docker_build_only.sh：同上验证： - 合并后触发 push 到 develop - 查看 Build Staging Web Image 日志，确认输出 Web cache bust: SOURCE_HASH=xxxxx - 修改 apps/web/ 下文件再次 push，确认 SOURCE_HASH 值变化且 vite build 执行
