Staged processing

The problem
Click Toggle sort. The displayed order changes, but both Filter passes and Sort passes increase even though the minimum filter did not change.
The pattern that fixes it
Click Toggle sort: filtering would run again unnecessarily → reuse the filtered rows and rerun only sorting. Then change Minimum: because the filter input changed, rerun both filtering and sorting so the displayed rows remain correct.
