Pull request overview

This PR upgrades the project’s baseline runtime/tooling to Python 3.14 and adjusts the dependency lockfile and codebase to match that new minimum version.

Changes:

• Bump minimum Python version to >=3.14 and update CI + Docker base images accordingly.
• Regenerate/update uv.lock for the new Python requirement (including marker/dependency pruning).
• Remove from __future__ import annotations across modules and apply a few small typing/asyncio cleanups.
