- PaginationCoordinator: 新增 textReflowable 快速进入路径，支持增量章节构建 与 staged 合并策略，避免整书一次性构建的主线程阻塞 - TextBookBuilder: 重构为支持单章构建与增量合并模式 - ChapterPageCounter: 优化分页计数逻辑，支持章节级分页缓存 - PageFrameFactory: 新增 CoreText 页面帧工厂，提升排版性能 - ReaderContext/ReaderRuntime: 适配增量分页状态管理 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
