git diff HEAD~1..HEAD -- piker/tsp/_anal.py

Added detect_time_ordering_errors() to return non-positive timestamp steps as structured rows. dedupe() now warns with those rows before sorting and duplicate removal erase the original ordering evidence.

git diff HEAD~1..HEAD -- piker/tsp/__init__.py

Exported the ordering detector through the public TSP package.

git diff HEAD~1..HEAD -- tests/test_tsp_analysis.py
