- RDPDFReaderPageView：完整页面视图移入 SDK（缩放画布、文字选择层、 选区放大镜、无障碍视口），并内置与 EPUB 一致的两套系统编辑菜单： 选区菜单（复制/划线/注释）、已有划线菜单（复制/注释|删除注释/删除划线） - RDPDFReaderPageViewDelegate：宿主只通过代理做数据持久化与打开业务界面 - 修复划线命中判定：点击点先归一化再与标注比例坐标比较 - 修复 tappedHighlight 残留导致选区菜单项被错误过滤的问题 - 主题应用改为纯颜色入参，SDK 不依赖 EPUB 主题类型 - RDPDFReaderHighlightOverlayView 恢复为纯绘制层，点击交互统一由页面视图处理 - Demo 删除 PDFDemoPageView（约 290 行），改为实现代理回调 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
