2.0.0

• Breaking Change: getUniqueIdentifier() has been converted to a static method.
  • You can now call it directly without creating an instance:

    final deviceId = await UniqueDeviceIdentifier.getUniqueIdentifier();

  • This change simplifies usage but breaks compatibility with the previous instance-based approach:

    // ❌ This will no longer work:
    final deviceId = await UniqueDeviceIdentifier().getUniqueIdentifier();
