List trace groups
Aggregate traces into groups using correlated sub-queries. Use this to find trace patterns and get aggregated trace metrics. Requires parallel arrays: query[], alias[], system[] with matching lengths. One alias must be 'root' to identify the root span query. Additional sub-queries filter traces where child spans match specific criteria. Systems: spans:all, httpserver:all, db:postgresql, log:error, etc. Returns grouped rows with dynamic columns. Use list_traces instead when you need individual trace details. Use list_span_groups instead when you don't need cross-span trace correlation.
