Fix typing annotation, optimize weighted_pipeline aggregation, clarify select comment

- __init__.py: use typing.List[str] instead of list[str] for broader compat
- datascience: precompute weighted_value column before groupby (faster, cleaner)
- prodev: clarify that SDK auto-lowercases select values
