pengxiao 6395ee3b49 feat: replace pymupdf image extraction with pdf2image + Heron layout detection
PDF image extraction now renders pages with pdf2image, detects figure
regions using docling-layout-heron (RT-DETRv2), and crops only the
detected pictures. Removes full-page fallback for text-only pages.
