lib.Types: Read abstractmethods via getattr()

LoadTypes._classes() reads the abstractmethods attribute of each class that inspect.getmembers() returns for its debug output. mypy 2.2.0 allows this, mypy 2.3.1 doesn't: It now types those classes as type[object] instead of Any. The attribute itself is only declared on the ABCMeta metaclass, so the direct access fails the type check.

Read the attribute through getattr() with an 'unknown' fallback string, and annotate the variable explicitly. The runtime behavior is unchanged, since the attribute exists whenever inspect.isabstract() is true, and the call satisfies the checker.

LoadTypes._classes() reads the __abstractmethods__ attribute of each class
that inspect.getmembers() returns for its debug output. mypy 2.2.0 allows
this, mypy 2.3.1 doesn't: It now types those classes as type[object]
instead of Any. The attribute itself is only declared on the ABCMeta
metaclass, so the direct access fails the type check.

Read the attribute through getattr() with an 'unknown' fallback string, and
annotate the variable explicitly. The runtime behavior is unchanged, since
the attribute exists whenever inspect.isabstract() is true, and the call
satisfies the checker.
