feat: add GPU optimization and fix TableData consistency

Browse Source 
GPU Optimization (Section 3.1):
- Add comprehensive memory management for RTX 4060 8GB
- Enable all recognition features (chart, formula, table, seal, text)
- Implement model cache with auto-unload for idle models
- Add memory monitoring and warning system

Bug Fix (Section 3.3):
- Fix TableData field inconsistency: 'columns' -> 'cols'
- Remove invalid 'html' and 'extracted_text' parameters
- Add proper TableCell conversion in _convert_table_data

Documentation:
- Add Future Improvements section for batch processing enhancement

## Future Improvements
The following improvements are identified but not part of this change proposal:
### Batch Processing Enhancement
- **Related to**: Section 3.1.2 (Enable batch processing for GPU efficiency)
- **Description**: Implement true batch inference by sending multiple pages or documents to PaddleOCR simultaneously
- **Benefits**: Better GPU utilization, reduced overhead from model switching
- **Requirements**: Queue management, memory-aware batching, result aggregation
- **Recommendation**: Create a separate change proposal when ready to implement
