* feat(flutter): identify Dart snapshot builds by pure APK parsing Add a flutter-provider family with one operation, identify_flutter_build, that reads an APK's lib/<abi>/libapp.so and libflutter.so through the hardened ZIP reader and reports build facts as observations: - The Dart VM snapshot hash, read 20 bytes after every snapshot magic (f5f5dcdc).
