Cherry-pick upstream PR #827 with conflict resolution for mod/master: - Add PngToBmpConverter library for PNG cover → BMP conversion - Add PNG thumbnail generation in generateThumbBmp() - Fix generateCoverBmp() PNG block to use effectiveCoverImageHref (consistent with mod's fallback cover candidate probing) - Add .png to getCoverCandidates() extensions - Use LOG_ERR macro in ImageToFramebufferDecoder (mod standard) - Upstream image converter refinements (ImageBlock, PixelCache, JpegToFramebufferConverter, PngToFramebufferConverter) Co-authored-by: Cursor <cursoragent@cursor.com>
