后端： - 新增 GET /version 版本检查端点（version.go + version.yaml） - 新增 GET /license/info 接口，返回门店授权信息 - 修复 GenerateOrderNo 并发重复单号：事务内加 FOR UPDATE 行锁 - 修复 ApproveStockOut 超卖竞态：预检和库存更新均加 FOR UPDATE - 修复 Product Create 并发 code 冲突：加重试逻辑，schema 加 UNIQUE KEY - 修复 Product Update 全字段覆盖：改用 selective Updates() - 挂载 ReadOnly 中间件（全局）+ AdminOnly（用户管理路由） - version.go 配置缺失时返回 500 而非静默降级 前端： - 新增自动更新检测（update_provider.dart）+ shell 更新 banner/弹窗 - 新增系统设置"关于"标签页：版本、授权、开发信息、意见反馈 - 新增离线缓存：所有 AsyncNotifierProvider 支持断网浏览历史数据 - 新增门店信息弹窗（点击左上角 logo 或右上角门店号触发） - 提取 AppConfig 统一管理 BASE_URL，支持 --dart-define 注入 - update_provider.dart 加 kIsWeb 保护，修复 Web 平台崩溃 - dev.sh 新增 stop 命令，修复 stop 误杀前端进程问题 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
