fix(tooling): cargo fmt + godot-cold-parse cache restore (gate round)

fmt: atlas_data_proxy.rs test code. godot-cold-parse: the cold parse re-seeds the class cache WITHOUT addon classes (gdUnit4's GdUnitTestCIRunner missing), leaving tests/run-godot unable to start (0 tests / 355ms — caught by the pre-push gate running the suite right after this script). The script now restores a full cache via a final --import pass before exiting; the cold verdict is unaffected.
