Describe the bug

When importing OrderedDict from the collections module in Python, any attempt to define or use a @cudaq.kernel results in an AttributeError. This appears to be a conflict between cudaq and the standard Python library, specifically the collections module. The issue makes it impossible to use OrderedDict alongside cudaq, which could affect projects relying on both.

Steps to reproduce the bug

import cudaq
from collections import OrderedDict

# Define our kernel.
@cudaq.kernel
def kernel(qubit_count: int):
    # Allocate our qubits.
    qvector = cudaq.qvector(qubit_count)
    # Place the first qubit in the superposition state.
    h(qvector[0])
    # Loop through the allocated qubits and apply controlled-X,
    # or CNOT, operations between them.
    for qubit in range(qubit_count - 1):
        x.ctrl(qvector[qubit], qvector[qubit + 1])
    # Measure the qubits.
    mz(qvector)

Expected behavior

The script should execute without errors, as importing OrderedDict from collections is a standard Python operation.

Instead, it fails with the following error:

AttributeError: type object 'collections.OrderedDict' has no attribute '__annotations__'

Is this a regression? If it is, put the last known working version (or commit) here.
