Qunits: queried units for database search

Summary: Introduce qunits—independent queried units representing canonical query results, decoupling declarative DB predicate semantics from presentation/aggregation. Keyword search is executed over a corpus of qunits treated as IR documents, enabling standard ranking models instead of ad-hoc DB ranking; prototype validates feasibility.
