    Pin pyarrow>=22.0.0 on Python 3.14 in highest-resolution constraints (#65216)
    
    Older pyarrow releases do not publish cp314 wheels on PyPI, so uv falls
    back to building pyarrow from source when resolving the highest versions
    of provider dependencies on Python 3.14 — which fails. pyarrow 22.0.0 is
    the first release shipping Python 3.14 wheels, so constrain it for that
    Python version when generating constraints.
