feat: optimize UI-TARS parser with coordinate conversion and action mapping

- Add action mapping for UI-TARS parser to convert action names to option.ActionName
- Implement bounding box to center point coordinate conversion for better accuracy
- Update coordinate normalization to handle coordinates > 1000 properly
- Enhance test cases to verify coordinate scaling and center point conversion
- Improve action argument processing with proper coordinate transformation
- Add comprehensive test coverage for coordinate conversion edge cases

Key improvements:
- Bounding box [x1,y1,x2,y2] now converts to center point [cx,cy] for actions
- Coordinate scaling properly handles different screen resolutions
- Action names are mapped through doubao_1_5_ui_tars_action_mapping
- Enhanced error handling for invalid coordinate formats
