Add eval_type_backport for Python 3.9 compatibility

nrempel · nrempel · commit 5167d60bc03c · 2025-12-14T09:16:02.000-08:00
Pydantic evaluates type annotations at runtime, and the `str | None`
union syntax isn't supported in Python 3.9. This package provides
backported type evaluation for older Python versions.
