shen 948004eed1 docs: 补充注释、修正过时文档、清理重复内容
源码注释:
- 为 ~60 个 Swift 文件补充缺失的 doc comment(file header、类型、属性、方法)
- 修正 4 处错误注释:翻页模式数量、搜索行为描述、手势识别器描述、悬空文档块

文档维护:
- 删除重复文档:WXRead/读书EPUB阅读器实现架构.md(与微信读书版完全一致)
- 合并重叠文档:阅读器规划.md → 阅读器功能开发计划.md(单一真值)
- 修正过时内容:所有文档中"四种翻页模式"→"三种",移除 horizontalCoverScroll
- 更新架构图:补齐 EPUBUI/ReaderController、Paging/、Typesetter/ 等子目录
- 更新 index.md 索引:新增开发计划和架构对比文档引用
