Update annotation parsing to work with PEP 649 in Python 3.14 #651
Description
It looks like accessing __annotations__ is likely to change in Python 3.13 3.14.

AFAICT none of this has actually landed in the cpython git repo yet - if/once it does we can start evaluating what changes are needed here.
