align Python version support with CI matrix

Python 3.9 reached end-of-life in October 2025. CI already tests 3.10
through 3.14, but pyproject still declared support starting at 3.9 and
classified up to 3.12 only.

- Bump requires-python to >=3.10 and update classifiers to 3.10-3.14
- Drop now-dead conditional deps (importlib-metadata < 3.8,
  typing-extensions <= 3.9)
- Bump ruff target-version to py310 (autofixes Optional[X] -> X | None)
- Simplify ParamSpec import in safe_sdk (now in typing on 3.10+)
- Simplify importlib.metadata import in __init__.py (no fallback needed)
