scripts/ is now a proper package (scripts/__init__.py, added to the wheel's packages), with each script registered under [project.scripts] using its bare dashed name (e.g. `uv run migrate-geant-steps`). Tests now import these modules normally instead of loading them by file path. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
