refactor: rename RDReaderView -> RDEpubReaderView, update pod config and docs
- Rename source module from RDReaderView to RDEpubReaderView - Move all source files from Sources/RDReaderView/ to Sources/RDEpubReaderView/ - Update podspec: RDReaderView.podspec -> RDEpubReaderView.podspec - Update Podfile, demo project, and CocoaPods config for new pod name - Delete old RDReaderView pod support files from ReadViewDemo/Pods - Add new RDEpubReaderView pod support files - Update documentation (API ref, architecture, UML, conventions, etc.) - Add FixedLayoutRotationTests - Update .gitignore: exclude .DS_Store, manual unpack backups, _ssoft-output
