+Check if GameAssembly.dll unlock offsets have shifted since last install.
+Uses the same logic as src/il2cpp_resolver.cpp: tries to resolve IsRobeUnlocked etc via
+il2cpp_class_from_name + hasCollectedAll, and also checks collectables.json full sets.
+If GameAssembly sha1 differs from DevourUnlocker.json:gameAssemblySha, warns to --repair.
