Standalone CLI that probes GPU (nvidia-smi), CUDA version, PyTorch,
scikit-learn, JAX, Optuna, RAM, and disk space — then generates
structured recommendations for model size, batch size, quantization,
and distillation feasibility.
Ships with 12-test suite (7 local + 5 Docker) covering graceful
degradation, all output flags, and a containerized no-GPU scenario.
