Bug: Incorrect Span Count Misleads Consumers

The total_spans field in the returned TraceData object is set to len(spans), but with the limit reduced to 1000, traces with more than 1000 spans will have an incorrect total_spans value that only reflects the number of fetched spans rather than the actual total. This misleads consumers like Seer and logging that rely on this metric.
