"""Nudge toward vitest tests when frontend JS source changes lack them.

Always exits 0 (non-blocking). Prints when staged JS source files under
src/.../static/js/ have no companion vitest tests staged. Sibling of
recommend-tests.py but vitest-specific so a Python-test-only commit
doesn't suppress the JS nudge.
