Windows Docker Desktop 本地开发实测：Vite 使用轮询挂载源码后可以热更新；Nest watch 能检测源码并编译，但 node:24-slim 不自带 ps，Nest CLI 的 treeKillSync 内部 spawnSync('ps',['-A','-o','pid,ppid']) 失败后只杀父进程，遗留旧API进程占用3000，导致EADDRINUSE且仍响应旧代码。修复为仅在Dockerfile.dev安装procps，保留Nest已有watch流程，不引入额外监听依赖。修复后已验证后端临时响应字段加入与撤销都自动生效，容器ID和启动时间不变。前端也通过无需刷新页面的DOM标记验证HMR。临时验证标记已恢复，不进入提交。 |
