// make CWD-local packages (e.g. the asset-side "scripts" package used by
// texture/screen renderers) importable. Embedded CPython builds sys.path
// from PYTHONHOME only; unlike the python CLI it does not prepend the
// working directory, and unlike Windows' getpathp.c it does not add the
// executable's directory either, so on POSIX "from scripts import ..."
// would otherwise fail. "." matches how the engine resolves all other
// assets (relative to CWD). Idempotent/harmless on Windows.
