fn each(&self) -> Result<Yield<Lister>, Error> {
        // Magnus handles yielding to Ruby using an unsafe internal function,
        // so we don’t manage the actual iteration loop ourselves.
        //
        // Since Ruby controls when values are pulled from the iterator,
        // and could potentially call `each` from multiple threads or fibers,
        // we wrap the underlying lister in `Arc<Mutex<_>>` to ensure thread safety.
        //
        // Multi-threaded iteration is rare in Ruby, but this design ensures thread safety.
