Daniel Johnson 697fa22d23 Detect string literals in | union annotations (crashes Python <3.14) ...

`"Foo" | None` fails at runtime on Python 3.10–3.13 because str doesn't
implement __or__. This only works on 3.14+ where PEP 749 defers annotation
evaluation. Add a check for this pattern alongside the existing conditional
import check so we catch it before it reaches users.
