📝 Description

Raise the SDK minimum to Python 3.11, remove the 3.10 classifier, and align CI and Black targets through Python 3.15. The standalone E2E workflow defaults to Python 3.13 and removes its EOL selector; the release cross-repo test runtime is also moved to 3.13. Remove Python 2-only fallback code while preserving the Python 3 behavior. This intentionally drops Python 3.10 support.

✔️ How to Test

pytest test/unit/: 517 tests passed on Python 3.11 and 3.15. The changed SDK files pass Black 26.10.1.
