"""Test the path sanitization in scripts/session-catchup.py.

Loads the real module via importlib (the filename has a hyphen, so it can't
be `import`-ed normally) and exercises its actual get_project_dir_claude,
instead of reimplementing the logic here. An earlier version of this file
reimplemented a fixed sanitizer for testing "to avoid import issues" — that
reimplementation was correct, but it meant the suite stayed green while the
shipped session-catchup.py (which it never touched) was still broken on
Windows. See CHANGELOG for the fix this guards.
