refactor: 重构项目为 MVC 架构并移除全局变量

- 将原有扁平目录结构重构为 MVC 分层架构： * src/core/: 核心业务逻辑（Model），完全独立于 UI 框架 * src/ui/: 界面组件构建（View），负责纯视觉展示 * src/controller/: 用户交互处理（Controller），连接数据与界面 * src/utils/: 底层工具函数，专注于系统调用和字符串处理 - 引入 AppContext 结构体统一管理应用状态，替代原有的全局变量模式 - 重命名并重新组织头文件，按功能模块划分到对应子目录 - 更新 CMakeLists.txt 以适配新的目录结构 - 同步更新 README.md 文档，说明新的架构设计
