feat: display images in chat request tree nodes#17024
Merged
Conversation
Render image thumbnails in chat request nodes for both attachment-flow images (from context variables) and paste-flow images (inline #imageContext variable parts). - Render context-variable images as thumbnails below the request text - Render pasted inline images as thumbnails replacing #imageContext text labels, positioned where they were pasted in the text flow - Deduplicate images across both sources - Fix doResolve() to preserve resolver-enriched arg instead of overwriting it with the caller's original arg, so resolved image data survives variable resolution - Fix getMessages() to extract images from inline resolved variable parts in addition to context variables, so pasted images reach the LLM - Fix clearPendingImageAttachments() ordering to run after sendRequest(), ensuring the pending image registry is available during variable resolution

What it does
Render image thumbnails in chat request nodes for both attachment-flow images (from context variables) and paste-flow images (inline #imageContext variable parts).
How to test
On Master:
Paste an image into the chat and see that the llm does not get the image.
With the fix, the llm gets the pasted image and we now render it also in the tree view.
All pasted images are shown in line where they were pasted.
All images added via context are shown grouped at the end of the message.
Follow-ups
We need to discuss how we want to handle images especially images in the context. To my understanding files in the context aren't directly send to the llm but just offered in a list that they are there. Images behave now different.
