Filter out thread 0 (coordinator) from skew calculation since it typically processes 0 rows in parallel operators, inflating the thread count. Raise the DOP 2 threshold from 75% to 80% — a 53/47 split is perfectly normal with only 2 worker threads. Fixes #73. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
