feat: parallelize lookup (Wiki+SearXNG) and include Wikipedia thumbnails

Runs the Wikipedia summary and SearXNG search concurrently and returns
both when available, so current-event questions aren't masked by a
generic role article from Wikipedia. When the Wikipedia summary includes
a thumbnail, it is cached through the existing image pipeline and
surfaced as an embeddable markdown snippet alongside the extract.
