重大架构改进： - 移除全局变量 xiaohongshuService，改用依赖注入 - 将代码按职责分离到不同文件： * app_server.go - 核心服务器结构 * types.go - 统一类型定义 * routes.go - 路由配置 * middleware.go - 中间件 * handlers_api.go - REST API 处理器 * handlers_mcp.go - MCP 协议处理器 - 将通用工具函数从 AppServer 方法改为独立函数 - 删除未使用的类型定义（LoginWaitRequest） - 修复 JSON 编码错误处理 优势： ✅ 更好的依赖注入模式 ✅ 清晰的职责分离 ✅ 提高代码可测试性 ✅ 符合 Go 最佳实践 ✅ 降低耦合度，提高内聚性 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Claude <noreply@anthropic.com>
