杭州明婳科技 08ed43385d fix(config): 模块 01 评审修复 + 对抗复核
config 模块(glm_check_report_module_01_config.md)11 项 finding 修复:

- H-config-1: Set(cfg) 用 mapstructure 重建 m.v,消除 Get/GetString/viper 视图分裂(C1)
- M-config-1: 热重载回调独立 recover,panic 不杀 watcher、不阻断后续回调(C9)
- M-config-2: DB SSL/TLS -- Postgres SSLMode(默认 prefer)+ MySQL TLS/TLSRootCA;
  database.ensureMySQLTLSRegistered 注册私有 CA 命名配置,fail-fast 不回退明文。
  O-1 文档准确性修正:同名注册会覆盖 master,改为 per-host 不同名 + 自建 replica DSN 指引
- M-config-3: App.Shutdown closeResources 停 configManager watcher(C7)
- M-config-4: Clone 切片/map 字段反射守卫测试
- M-config-5: WithConfig/WithConfigPath 全局可见性文档强化
- L-config-2: watchLoop 增 ctx 逃生通道,StopWatcher cancel+Close 双重退出
- L-config-3/4/5/6: Validate 连接池交叉校验、哨兵 errors.New、去冗余 TrimSpace、nil receiver 防御

含契约级回归测试(同源一致性/生命周期闭环/扩展点防御),-race/vet/build 全绿。
附 module 01 评审报告 + 全局结构图 + 扫描收敛协议。
