test_slugify.py

"""Regression tests for utils.slugify (Issue #30 / CCC8).

Historically ``scripts/export.py`` used ``isalnum()`` (Unicode letters preserved)
while ``api/export_api.py`` used ASCII-only ``[^a-z0-9]+``. The canonical
implementation matches the API for portable zip / download filenames.
