The previous commit reads __abstractmethods__ via a getattr() with an empty frozenset fallback, because in mypy 2.3.1 the scanned classes are typed as type[object], which does not declare the attribute. Add is_abc_class() as a TypeGuard, and skip the classes it rejects with a debug line: LoadTypes now yields only ABC-derived classes. The guard narrows to the classes that carry the attribute, so that the debug line can now read __abstractmethods__ directly. The command loaders are unaffected: every class they load is derived from AbstractCmd, and hence from ABC. For loads that rely on the name filter alone, plain classes are now skipped instead of being yielded.
