Python 3.14 is not supported yet, one of our core dependencies is not compatible.

[skinkie]

What is the core component failing?

Hey,

untokenize is a dependency of docformatter and gets only installed if the cli extra is installed.

It looks like the dependency is unused in docformatter at all: https://github.com/PyCQA/docformatter/pull/325

Would be good to support python 3.14.
