Summary of ChangesHello @aibysid, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request enhances the ChatOpenRouter node by integrating multimodal capabilities, specifically allowing users to provide image inputs to OpenRouter models. It introduces new configuration options for image handling and leverages a dedicated wrapper class to manage this functionality, aligning with existing multimodal implementations within the system.

Code Review
This pull request adds image upload support to the ChatOpenRouter node, following a similar pattern to the existing ChatOpenAI implementation. The changes are well-structured and introduce new UI fields for enabling image uploads and setting resolution. My review includes a couple of suggestions to enhance error message clarity and improve TypeScript type safety for better robustness. Overall, this is a solid contribution.

Concatenating the exception object directly with a string can lead to unhelpful error messages like [object Object]. It's better to use the exception's message property if it's an Error instance, or convert it to a string otherwise, to provide more informative error details.

The multiModalOption property is declared but not initialized in the constructor. It's set later via setMultiModalOption. This can lead to runtime errors if other methods access it before it's set. Using a definite assignment assertion (!) makes it clear that this property will be initialized elsewhere, improving type safety and code clarity.
