NDArray doesn't handle types with custom core schemas properly

[NeejWeej]

Describe the bug
NDArray type does not handle classes with custom pydantic core schemas properly

To Reproduce

# /// script
# dependencies = [
#   "csp",
#   "ccflow>=0.5.1",
# ]
# ///


from csp import Enum
from ccflow import NDArray
from pydantic import TypeAdapter

import numpy as np

class MyEnum(Enum):
    X = Enum.auto()
    Y = Enum.auto()

ta_my_array = TypeAdapter(NDArray[MyEnum])

my_array = ta_my_array.validate_python(np.array([MyEnum.X]))
print(f'{my_array = }')
print(ta_my_array.dump_json(my_array))

Expected behavior
This should serialize properly

Error Message
Reading inline script metadata from /test_ccflow.py
my_array = array([<MyEnum.X: 0>], dtype=object)
