… 3.11

• requirements.txt listed python-dateutil, but nothing imports it and pyproject.toml never declared it.
• Add Python 3.14 to the CI matrix and tox envlist, and update the docs that list the tested versions.
• mypy.ini targeted 3.12 while requires-python is >=3.11, so mypy could accept syntax or stdlib APIs the minimum version lacks.
