📄 Description

feat: add citation sources for fetch_url tool results

This recreates the already existing behaviour where when I manually add a website to a chat, it IS COUNTED as a source, so model-fetched URLs should be too

URL fetches now produce clickable citation sources in the UI, matching the existing behavior of search_web and knowledge file tools. When a model calls fetch_url during native tool calling, the fetched URL appears as a citable source with a content preview, giving users full transparency into what pages the model referenced.
