Partitioned at the section banners each file already used, into ten new
modules named for what they cover. python_pkg/code_tutor is now entirely
under the cap, from thirteen violations.
The splitter copies the whole original header into each new file and
lets ruff's F401 pass prune it - 59 imports removed correctly, versus a
hand-written import block failing on every earlier test split today.
That does not cover module-level helpers: _make_verifier sat between two
banners and was left behind by its callers, so it moved to conftest.py,
taking test_verifier.py's shadowing copy of _make_live_mock with it.
No patch string changed. Pass count is 217 before and after.
