refactor(mypy) Adopt Python 3.10 typing idioms

- replace remaining Optional/Union patterns with PEP 604 unions aligned to the new baseline
- guard typing_extensions imports under TYPE_CHECKING while dropping obsolete version branches
- add explicit strict=False to zip-based format parsing to satisfy Ruff B905
