- Remove duplicate ReaderMetadata interface from comic/image-parser.ts
- Remove duplicate ReaderMetadata interface from pdf/pdfjs-wrapper.ts
- Use centralized interface from types/reader.d.ts instead
- Reduces code duplication and ensures type consistency across formats
This change ensures all format parsers use the same canonical
ReaderMetadata interface, making the codebase easier to maintain
and preventing type drift between different file formats.
