- Refactor chapter runtime: replace window coordinator/snapshot with warmup orchestrator
- Update EPUB core: parser, reading session, JS bridge, navigator layout
- Update reader controller: data source, location resolution, persistence
- Update chapter runtime: data cache, loader, runtime store, disk cache, warmup orchestrator
- Remove deprecated navigation state machine and pagination state
- Update text rendering: book cache, HTML normalizer
- Update UI: text content view, dark image adjuster, text selection controller
- Update settings and reader configuration
- Add CODE_REVIEW.md and AUDIT_FINAL.md documentation
- Update pod dependencies (remove SSAlertSwift, SnapKit)
- Update podspec and pod configuration files
