A port of tools/prepare_native_client.py and the helpers it imported from
lab.py and the test_*_parity.py modules: the player's pinned game files are
imported and checked against research-lock.json, the client's assets and data
copied, the vanilla exporters compiled and run with the JDK (JAVA_HOME, the
PATH, or java_home on macOS, at the pinned java_major), and the resources and
their manifest written byte for byte as the script wrote them, with its
sha256-keyed skips. tools/compare_prepare.py checks that against the Python
preparer.
