[Bug 2160284] [NEW] cmd2 4.0.0+ds-2 FTBFS in stonking: mkdocs/pygments html.escape issue with Python 3.14

Public bug reported:

The cmd2 package fails to build from source in stonking on amd64.

AI early diagnosis:
Documentation build fails with mkdocs/pygments because html.escape receives a NoneType filename argument in Python 3.14. This is likely a compatibility issue between pygments/mkdocs and Python 3.14, requiring changes in those upstream projects rather than cmd2 itself.

** Affects: cmd2 (Ubuntu)
     Importance: High
     Assignee: Zineb Zaadoud (zineb)
         Status: Triaged
