    chore: Disable C interop tests when an incompatible version of Python is 
installed (#152)
    
    ## What's Changed
    
    This disables the C interop tests for now as they're failing due to a
    pythonnet incompatibility with Python 3.14. These should be reenabled
    before shipping a new release, hopefully by being able to take a new
    version of pythonnet.
