Remove "from __future__ import annotations"

[ulgens]

This feature doesn't seem to be useful with Python 3.12+. It seems the feature itself already became obsolote with Python 3.14: https://www.reddit.com/r/learnpython/comments/1psteqc/comment/nvc6aku/

I'm not going to say I fully understand the effects of the removal, but so far it doesn't break anything and I don't see any reason to keep it in place, and enforce as default. Can be revisited in case of a problem.

Another +1 for the removal: Having it enforced results with it being inserted in code snippets in the docs too. This can be handled with an exemption config, but I'll prefer removing it for the reasons I just explained.

Changes:

• Dropped Ruff/isort required-imports configuration that enforced the future import.
