1. Configurable chapter window size (onDemandChapterWindowSize: 3-15) - Parameterized window radius in RDEPUBChapterRuntimeStore - Updated RDEPUBChapterWindowCoordinator to use configurable radius - RDEPUBChapterWindowSnapshot.from() accepts chapter array instead of fixed prev/next - Even numbers round up to odd (4→5), min 3, max 15 2. Configurable metadata parsing concurrency (metadataParsingConcurrency) - Default equals CPU core count - Parallel execution via OperationQueue in paginateMetadataOnly - Each worker creates independent builder instance - NSLock protects result aggregation 3. Per-chapter and total wall-clock timing instrumentation - Separated render vs I/O timing per chapter - Summary log with wallClockMs, renderTotalMs, writeTotalMs, avgRenderMs - Timing stored in RDEPUBReaderContext for test access 4. UI automation test infrastructure - Added --demo-window-size, --demo-concurrency, --demo-clear-cache launch args - DemoReaderState exposes windowSize, parseMs, parseConcurrency - ConfigurableWindowTests: 5 test cases for window size 3/5/15 - ConcurrentParsingTests: 4 test cases for concurrency 2/4 - MetadataParseBenchmarkTests: serial vs parallel benchmark 5. Bug fixes - Fixed page snap-back during background parsing (isUserInteracting check) - Reduced BookPageMap refresh frequency from 16 to 32 chapters - Moved waitForReadingInteractionToSettle outside operation loop 6. Design doc: dual-layer PageMap (estimated + precise mixed)
