Add imaging/document primitives: PNG codec, rasterizer, GIF, PDF
- Pure-JS PNG decode (grey/RGB/palette/alpha) + RGBA encode, CRC-checked;
decode verified byte-identical with ImageMagick
- Software rasterizer: shapes, arrows, blur, highlight, magnify, tooltip,
number badges, cursor, bitmap text (vendored public-domain font8x8),
crop/resize, focused-view rendering
- GIF89a encoder with LZW (cross-validated pixel-for-pixel against
ImageMagick decode) + NETSCAPE looping
- Minimal PDF 1.4 writer: pages, fonts, rects, images, outlines, valid
xref; rendering validated under Ghostscript
- 12 imaging workflow tests (35 total)
