[BUG]: structured doesn't work with python 3.14 due to annotation changes.

Reproducer

I don't have a minimal reproduction case, but I suspect lots of unit test failures happen if they're run under 3.14. I assume this is related to https://docs.python.org/3/whatsnew/3.14.html#whatsnew314-deferred-annotations.

Removing the metaclass from structured/structured.py's Structured class seems to fix it for me, but I don't need the multiple anonymous _: pad[...] constructs that StructuredMeta attempts to support.

Thanks for bringing this to my attention - I hadn't bothered to upgrade to Python 3.14 yet since all of the projects/tools I use have dependencies that haven't been updated for it yet.

Question for you, if you add from __future__ import annotations to the beginning of each source file does this fix the issue? If not I'll have to dig into it more deeply.
