- fixed the CI collection errors and implemented a local pre-commit hook to automate testing.

scripts/diagnose_collapse.py was still attempting to import the missing function, causing a collection error during the pytest run.
src/spatial_transcript_former/recipes/hest/dataset.py contained a docstring reference that was confusing the documentation/test collection.
