danielhanchen 389303d3de Harden sandbox classifier against round-12 mro/attrgetter/loader bypasses
Static classifier:
- Flag mro().pop(i) / __mro__.pop(i) base-class extraction alongside the subscript and __getitem__ forms.
- Normalize operator.attrgetter('name')(obj) as attribute access whether or not the result is immediately invoked, so attrgetter('__closure__')(open)[0] gadget recovery is caught.
- Resolve a container-hidden open alias (o = [open][0]; o('../../etc/passwd').read()) as a read callee.
- Fail closed on an opaque read path assembled from obfuscation primitives (open(''.join(map(chr, ...))).read()), matching the exec-payload obfuscation policy.
- Treat cd behind the command / builtin shell wrappers as a cwd escape before allowing a relative redirect.
- Block importlib file loaders as execution sinks (SourceFileLoader(...).load_module(), spec.loader.exec_module(...)).
- Add the in-cluster Kubernetes service-account credential path to the sensitive-read list.

Adds TestRound12Bypasses covering each vector plus benign controls.
