Raises `RuntimeError` if the outcome has no exception.

We're going to leverage GitHub release directly.

Remove Python 3.9 from CI matrix, setup.cfg classifiers, tox envlist,
mergify checks, and bump python_requires to >=3.10.

Inline code that was gated behind sys.version_info checks:
- Use slots=True directly in dataclass decorator (3.10+)
- Use futures.Future[t.Any] directly (3.9+)
- Remove redundant version checks and imports in tests

* improve annotations

* ruff format

* fix for py311
