Subject: [PATCH] CI(Core): spoof torch.cuda before importing unsloth_zoo in
 llama.cpp smoke

The previous push of the install_llama_cpp-based smoke failed across
all three cells with:

  File "unsloth_zoo/device_type.py:220" in get_device_type
    raise NotImplementedError("Unsloth cannot find any torch
    accelerator? You need a GPU.")

unsloth_zoo/__init__.py calls device_type.get_device_type() at module
load. On the GH ubuntu-latest CPU-only runner this raises before any
of our code runs. The pytest shims sidestep this by importing
tests/_zoo_aggressive_cuda_spoof.py first; the inline `python <<PY`
block was missing the same harness.

Apply the spoof at the top of the inline script so torch.cuda.is_
available() returns True before the unsloth_zoo import. We never
actually run CUDA tensor ops in this step -- just clone + cmake +
binary --help -- so the spoof is sufficient.
