Bumps cython from 3.1.3 to 3.1.4.

Changelog

Sourced from cython's changelog.

3.1.4 (2025-09-16)

Features added

  • Declarations for the new PyUnstable_*() refcounting C-API functions in Py3.14 were added. (Github issue :issue:6836)

Bugs fixed

  • The monitoring code could crash on tracing. (Github issue :issue:7050)

  • Initialising the monitoring code could fail with a CPython exception. See nedbat/coveragepy#1790

  • Optimised integer shifting triggered undefined behaviour in C. (Github issue :issue:7089)

  • Deallocating objects that inherit from external types defined in pxd files could run into an infinite loop. (Github issue :issue:7143)

  • A reference to metaclasses could be leaked on instantiation. (Github issue :issue:7130)

  • (Unlikely) error handling during empty builtin container tests was ineffective. (Github issue :issue:7190)

  • Generated *_api.h files used potentially unknown Cython configuration macros. (Github issue :issue:7108)

  • cythonize() avoids parallel compiler runs on systems using spawn() in multiprocessing. Patch by Marcel Bargull. (Github issue :issue:3262)

  • The @cython.ufunc decorator was missing in type checker stubs. Patch by jayClean. (Github issue :issue:7109)
