Phase 1: Context 拆分 - 新增 RDEPUBReaderState/RDEPUBReaderEnvironment/RDEPUBReaderServices - RDEPUBReaderContext 改为过渡门面，代理到 State/Environment/Services Phase 2: Runtime 拆分 - 新增 RDEPUBPresentationRuntime 处理分页状态管理 - 新增 RDEPUBChapterWarmupOrchestrator 处理章节预热与加载编排 - RDEPUBReaderRuntime 从 1277 行收缩，公共 API 转发到新 facade Phase 0.5: 性能优化 - prepareOnDemandChapter 支持异步模式（allowSynchronousLoad: false） - extendPartialBookPageMapIfNeeded 改为 DispatchGroup 并发加载 - RDEPUBChapterOffsetMap.cfiMap 加 NSLock 保护数据竞争 - CFI Map 构建延迟到后台队列（scheduleDeferredCFIMapBuildIfNeeded） - RDEPUBTextPageRenderView 引入静态位图缓存 - RDEPUBTextContentView 新增 loadingSpinner 占位页 Phase 3: 状态机 - 新增 RDEPUBNavigationStateMachine（含 DEBUG 合法转换校验） - 新增 RDEPUBPaginationState 记录分页来源 Review 修复 - makeSummary 重复方法合并 - ensureNavigationTargetAvailable 同步路径加注释标记 UI 测试 - 新增 AsyncChapterLoadingTests（20 个测试，覆盖全部架构整改场景） - 跨章节翻页、延迟 CFI、状态机、内存警告、预加载、位置恢复等
