Google News RSS excerpts use double non-breaking spaces followed by the publisher name (e.g. "...habitat News-Medical"). When the source field is "news.google.com" rather than the actual publisher, the exact-match logic can't strip it. This adds a regex fallback that catches trailing nbsp-separated capitalized names.
