query
Resolves the diamond: both PropositionStore and VectorSearchCapable declare query. This explicitly routes to the base store's implementation; concrete stores can still override for backend-level filtering.
Query propositions, optionally guaranteeing loaded provenance. With withProvenance = true every result has its Proposition.provenanceEntries populated (at extra read cost); the default delegates to the lean query. See the provenance read contract on PropositionStore.findAll.
