reugenio f9189253d7 feat: v0.3 - Image support (JPEG embedding)
Phase 3 - Images:
- JPEG parser with direct DCT passthrough (no re-encoding)
- PNG metadata extraction (full embedding pending)
- Page.image() for drawing images at position
- Page.imageFit() for auto-scaling with aspect ratio
- Pdf.addJpegImage() / addJpegImageFromFile()
- XObject generation in OutputProducer

New modules:
- src/images/mod.zig - Image module exports
- src/images/image_info.zig - ImageInfo struct
- src/images/jpeg.zig - JPEG parser
- src/images/png.zig - PNG metadata parser

New example:
- examples/image_demo.zig - Image embedding demo

Stats:
- 66 unit tests passing
- 4 working examples
