danielhanchen 6baedd40d5 Harden sandbox classifier against round-11 obfuscation and higher-order sink bypasses
Static classifier:
- Flag __getattribute__/__getattr__ with a non-foldable (runtime-assembled) attribute name as an obfuscated gadget access.
- Recognize POSIX noclobber redirect targets (>| path) in the shell redirect scanner.
- Detect a container-wrapped compile() code object passed to types.FunctionType.
- Flag mro().__getitem__(i) / __mro__.__getitem__(i) base-class extraction alongside the subscript form.
- Scan shell command strings (os.system / subprocess shell=True / getoutput) for embedded sensitive-file reads.
- Treat a default-parameter value that is a dangerous callable (def f(e=exec)) as a sink alias.
- Normalize a trailing .__call__ for shell/import/deserializer sinks (os.system.__call__, __import__.__call__, pickle.loads.__call__).
- Resolve a container-unwrapped sink assigned first (s = [os.system][0]; s(...)).
- Look through no-op pathlib methods (resolve/absolute/expanduser) when resolving a read receiver.
- Recognize from-imported shutil copy sinks (from shutil import copy as c).
- Extend the higher-order first-class-value check to shell and deserializer sinks (map(os.system, ...), partial(subprocess.getoutput, ...), map(pickle.loads, ...)).
- Normalize operator.attrgetter('name')(obj) as attribute-access obfuscation.

Adds TestRound11Bypasses covering each vector plus benign controls.
