Ignore PEP 649 + 695 implementation details in stubtest

[cdce8p]

PEP 649 added __annotate__ and PEP 695 __classdictcell__. At the moment it looks like 649 will be enabled with 3.14 at which point stubtest would complain about these. It probably makes sense to add them to the ignore list now.

__annotate__ is from PEP 649, not 695. __classdictcell__ does come from PEP 695 (so it's already in 3.12+), but is used only during class body execution and I don't think stubtest should see it. Did you encounter problems with it?

Seems I mixed them up again. Sorry about that.

Did you encounter problems with it?

I did ran the test suite with Python 3.14.0a4 yesterday. These were two of the test failures. IIRC they had been there since some time, maybe 3.14.0a1?
