shen 54798ba578 refactor: 添加中文注释 + 优化模块结构
- 给全部 78 个 Swift 源文件添加详细的中文注释(文件级、类级、方法级)
- 删除 LegacyRDReaderController/ 死代码目录(16 文件 4592 行)
- 根目录翻页容器文件移入 ReaderView/ 目录
- Resources/ 移入 EPUBCore/Resources/(与使用者归属一致)
- RDEPUBTextIndexTable.swift 移入 EPUBTextRendering/(消除反向依赖)
- RDURLReaderController.swift 移入 EPUBUI/(入口控制器归入 UI 层)
- 更新 podspec 资源路径
