Search results were sorted purely by seeder count, so a season pack only
won out over a single-episode release by accident. Season packs already
clear every missing episode of that season in one grab and go through the
same seeder/quality gate as anything else (an unviable pack still gets
rejected there and iteration falls through to the next candidate) — so
sorting packs first, seeders as the tiebreaker, is a strict improvement
with no new risk. Shared by both the automated search cycle and the
manual-search candidate list.
