refactor(reader): 重构高亮选区绘制架构，对齐 WXRead 实现方案
- 移除 RDEPUBSelectableTextView，改用原生 UITextView - 新增 NSAttributedString 自定义属性（com.rdreader.highlight/underline）注入高亮 - RDEPUBTextPageRenderView 统一绘制高亮背景、文字和选区 - RDEPUBTextSelectionController 精简，选区矩形传递给 RenderView 绘制 - 新增高亮选区复刻 WXRead 实现方案文档 - UI 测试适配新架构 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
