__annotate__ as an implicit global is version-gated (Py3.14+)

Absent before 3.14

__annotate__ is never present in the global namespace on Python <3.14.

Present in 3.14+

The __annotate__ global may be present in Python 3.14, but only if at least one global symbol in the module is annotated (e.g. x: int or x: int = 42). Currently we model __annotate__ as always being possibly unbound on Python 3.14+.
