Display book cover image as background in the Continue Reading card on the home screen, improving visual identification of the current book. Key changes: - Add thumbnail generation (thumb.bmp) for EPUB and XTC/XTCH files - Uses same dithering/scaling algorithms as sleep screen covers - Target size: 240x400 (half screen) for optimal Continue Reading card fit - Add JpegToBmpConverter::jpegFileToBmpStreamWithSize() for custom target sizes - Add GfxRenderer::copyStoredBwBuffer() and freeStoredBwBuffer() for framebuffer caching to maintain fast navigation performance - Add UTF-8 safe string truncation for Korean/CJK text in title/author display - Draw white boxes behind title/author text for readability over cover image - Increase HomeActivityTask stack size to 4096 for cover image rendering - Add bounds checking in XTC thumbnail generation to prevent buffer overflow
