MemoryShield class
Singleton manager that tracks all active secure containers and can mass-wipe.
Tracks SecureString, SecureBytes, and SecureValue instances and provides lifecycle-aware auto-dispose when the app backgrounds.
MemoryShield().init(MemoryShieldConfig(
autoDisposeOnBackground: true,
));
MemoryShield().bindToLifecycle();
// On logout:
MemoryShield().disposeAll();
