feat: 完成后端中间件系统完善
## 🛡️ 新增功能 - 实现完整的CORS中间件，支持开发/生产环境配置 - 实现请求日志中间件，完整的请求生命周期记录 - 实现全局错误处理中间件，统一错误响应格式 - 创建中间件管理器，支持链式中间件和配置管理 ## 🔧 技术改进 - 更新配置系统支持中间件配置 - 修复go-zero日志API兼容性问题 - 创建完整的中间件测试用例 - 编译测试通过，功能完整可用 ## 📊 进度提升 - 项目总进度从42.5%提升至50.0% - 中优先级任务完成率达55% - 3个中优先级任务同时完成 ## 🎯 完成的任务 14. 实现 CORS 中间件 16. 实现请求日志中间件 17. 完善全局错误处理 Co-authored-by: Claude Code <claude@anthropic.com>
