前端: - src/srv/api → src/api，按域分文件夹(auth/cluster/host/storage/deployment/collector) - 新增 http.ts 引擎(http.get/post/put/delete)，域模块改用语义化调用 - index.html 增加 favicon(匹配应用 logo 的 emerald + Activity 脉冲) 后端分层增强(保留包名): - 新增 repository/：从 models 拆出 JsonDB 持久化层(InitDB/GetDB/Shutdown/RequestSave) - 新增 dto/：从 controllers 抽出各域请求契约(带 binding 校验) - 新增 pkg/crypto、pkg/jwt：从 utils 拆出安全原语(外部 jwt 别名 jwtv5 避免冲突) - models 只留领域实体 + sanitizer；utils 只留 gin/应用相关(response/errors) v2 优化移植与缺陷修复: - 移植密钥分离/SSH TOFU/并发写安全/Loki 生产级配置/Docker 加固 - 修复 deployment.go 并发丢更新、Helm values 重复键、EncryptField 哨兵、loki-gateway 端点等审计缺陷 - 实现真正的优雅关停(main.go http.Server + signal + repository.Shutdown) - 修复登录契约:后端返回 accessToken，前端 auth.ts/Login.tsx 对齐 - 补 crypto/jwt/repository 单元测试(含并发写回归) 验证: go build/vet/test 全绿；npm run build 通过；登录→鉴权→优雅关停冒烟通过 Co-Authored-By: Claude <noreply@anthropic.com>
