• The function TfLiteOperatorCreate is now declared twice in this C header (once for three parameters and once for four), which causes a name collision. Restore a unique name (e.g., TfLiteOperatorCreateWithData) for the overload that accepts user_data.

• The metadata sets Exclude Android: 1 for an ARM64 Android library, which will prevent it from being included in Android builds. Set this flag to 0 to ensure the plugin is packaged correctly for Android.
