Pulls in the dataset-autosave-corruption fix (policyengine.py #450): a region-scoped dataset copy no longer overwrites the shared source dataset file it was filtered from. Relocked uv.lock (also syncs the stale project version 3.43.6 -> 3.43.7 already in pyproject). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
