This reverts commit 1d63c73be4fca63d660488e6efab703f51405fc7.

* Fix numpy requirement for Python 3.14 on ARM64 Windows

Change numpy==2.4.0 to numpy>=2.4.0 for Python 3.14+ to allow
pip to install numpy 2.4.1 or later versions, which are available
for Python 3.14 on ARM64 Windows (MSYS2) where numpy 2.4.0 is not.
