feat: 支持加密 EPUB、试读墙、工具栏定制与朝向锁定
- 新增 RDEPUBResourceDataProvider 解密钩子协议 + 访问登记表，收敛章节 HTML/ 图片/内联 CSS/脚注/封面/图片查看器/正文取图等读取点，scheme handler 对加密书 禁用流式分支；新增 RDEPUBDecryptingImageAttachment 解密 DTCoreText 图片附件； RDEPUBReaderDependencies.live(resourceDataProvider:) 便捷注入。明文书零影响。 - 试读墙：configuration.trialPolicy + delegate epubReaderTrialWallView/ DidReachTrialWall，UI 由宿主提供（RDEPUBReaderController+Trial）。 - 工具栏定制：RDEPUBReaderTop/BottomToolViewProtocol 协议 + dependencies 工厂注入， 内置栏已 conform，configureTopToolView 改协议类型。 - 朝向锁定：RDEPUBMetadata.orientation（OPF rendition:orientation 主， iBooks display-options 兜底）+ RDEPUBReaderController+Orientation 重写支持朝向、 打开后主动转向。 注：RDEPUBReaderController+LocationResolution / PaginationCoordinator 为本次改动前 即存在的工作区修改，一并纳入。 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
