List distinct values for a catalog entity
Paginated, searchable list of distinct values for a specific entity (or semantic concept) within an application. Useful for populating filter dropdowns in the Trace Explorer UI.
entity_type is always required. Provide exactly one of name (exact attribute key) or semantic_name (resolves to every attribute key mapped to the given concept, making the values lookup SDK-agnostic).
