windows 11 with python 3.14 support

Reproduce the opencv-python installation on Windows 11 with Python 3.14 using the reported pip output. Start by investigating NumPy 2.2.6's source-build path and the Ninja subprocess failure with WinError 5; done means establishing whether a compatible installation works or clearly documenting the support limitation.
