Poor compatibility with Python 3.14+NumPy 2.3.3

This issue was raised last year, but the version involved was Py 3.10 and 3.11, so an additional issue is being proposed for compatibility with the new version.

Python 3.14.0 (tags/v3.14.0:ebf955d, Oct  7 2025, 10:15:03) [MSC v.1944 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.3.3 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

after downgraded to np1.26.4:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
opencv-contrib-python 4.13.0.90 requires numpy>=2; python_version >= "3.9", but you have numpy 1.26.4 which is incompatible.
opencv-python 4.13.0.90 requires numpy>=2; python_version >= "3.9", but you have numpy 1.26.4 which is incompatible.

（note：it requires numpy2 while installation, but numpy 1 during runtime）
（WHAT THE F**K IS THIS???

No repository files or tests are named. Start by reproducing the cv2 import with Python 3.14 and NumPy 2.3.3, then inspect the package build and dependency metadata for the generated wheel. Done means the package imports successfully and its declared NumPy requirements match runtime compatibility.
