Document Intelligence Model Interfaces

Pluggable model interfaces for document understanding:
- OCRModel: Text recognition
- LayoutModel: Layout detection
- ReadingOrderModel: Reading order determination
- TableModel: Table structure extraction
- ChartModel: Chart/graph understanding
- VisionLanguageModel: Multimodal understanding
