rag.usp_ReviewQueue

-- İnceleme kuyruğu (spec 2026-09-30-alt-proje-2 §E, mockup 23): DBA kararı bekleyen işler tek listede. Idempotent.
-- (1) Biten analizin kararsız önerileri (analiz başına bir satır), (2) Pending/Unsure plan değişim vakaları.
-- Script'i olmayan öneri de onay/red alır (vaka hafızası; canlı #1178-1180): sayılır, yalnız "Uygulandı" olamaz.
-- Bedel: öznenin (sorgu ya da nesne) son 7 gündeki günlük ortalama toplam süresi (sn/gün); manuel analizde yok.
