fix(openai): handle OpenRouter image generation responses
b948555 
- Add support for OpenRouter's image generation API response format
- Extract images from OpenRouter's `choices[0].message.images` array
- Convert images to LangChain's Multimodal.Image content blocks
- Add unit tests for single image, multiple images, and text-only responses
- Use proper TypeScript types for content blocks

OpenRouter returns generated images in a separate `images` array rather than
within the message content. This fix ensures these images are properly
extracted and converted to LangChain's standard multimodal message format.

Fixes: #8791
