Summary

Fixes TypeScript compilation errors in #1784 in Lfm2VlImageProcessor and MgpstrProcessor that were causing the build to fail.

Changes

Lfm2VlImageProcessor

• Added Lfm2VlImageProcessorResult typedef that extends ImageProcessorResult with additional properties (pixel_attention_mask, spatial_shapes, and optional image_rows, image_cols, image_sizes)
• Added proper JSDoc return type annotation to _call method: @returns {Promise<Lfm2VlImageProcessorResult>}
• Fixed array type declarations for all_image_sizes and all_original_sizes from number[][] to HeightWidth[] to match the expected tuple type
• Removed incorrect Record<string, any> type annotation on result object

MgpstrProcessor

• Renamed batch_decode to decode_logits to avoid conflict with base class method
• Updated JSDoc to clarify the method converts model prediction logits (not token ids)
• Updated corresponding test calls to use the new method name

Testing

• pnpm build completes successfully without TypeScript errors
• Existing tests pass
