fix(deps): require eval-type-backport on Python 3.9

cubehouse · claude · cubehouse · commit 63d44315bd59 · 2026-04-15T00:14:00.000Z
Pydantic v2 evaluates PEP 604 union annotations (X | None) at model
construction. Generated models use this syntax; on Python 3.9 the
runtime lacks PEP 604 support, so pydantic needs eval-type-backport
to interpret the annotations. No effect on Python 3.10+.
