Correct fix. The previous code returned the metadata summary ("Fetched N bytes from URL...") in ForLLM but omitted the actual fetched text content, which means the LLM could see that a page was fetched but could never read the content. The fix appends the actual text to the ForLLM field so the LLM can reason over the fetched content.

LGTM.
