Structured aggregate metrics with full statistical aggregates (avg, min, max, sum, count). Keys are scorer UUIDs for scorer-backed metrics (matching available_columns column IDs after stripping the 'metrics/' prefix) and raw strings for system metrics (e.g. 'duration_ns', 'cost'). Present only when use_clickhouse_run_aggregates flag is enabled.
