 Added predicate-based entity filtering via POST /entities/by-query endpoint.
 
-Supports `$all`, `$any`, `$not`, `$exists`, `$in`, and `$hasPrefix` operators for expressive entity queries. Integrated into the existing `queryEntities` flow with full cursor-based pagination, permission enforcement, and `totalItems` support.
+Supports `$all`, `$any`, `$not`, `$exists`, `$in`, `$hasPrefix`, and (partially) `$contains` operators for expressive entity queries. Integrated into the existing `queryEntities` flow with full cursor-based pagination, permission enforcement, and `totalItems` support.
