Subject: [PATCH 2/3] Fix UnboundLocalError in test_numpy_results_paged

Initialize `count` variable before the for loop to prevent
UnboundLocalError when the loop doesn't execute. This follows
the same pattern already used in verify_iterator_data().

Subject: [PATCH 3/3] Fix NumPy 2.0 compatibility in numpy_parser

The `ndarray.newbyteorder()` method was removed in NumPy 2.0.
Use `arr.view(arr.dtype.newbyteorder())` instead, which is compatible
with both NumPy 1.x and 2.x.

This fixes the failing numpy protocol handler integration tests
that started running after numpy was added to dev dependencies.
