canonicalize_gpu_name 

canonicalize_gpu_name(name: str) -> str

Canonicalize GPU name for use as a platform identifier.

Converts to lowercase, replaces spaces and hyphens with underscores, and maps known variant names to their canonical form via _GPU_NAME_ALIASES. e.g., "NVIDIA H100 80GB HBM3" -> "nvidia_h100" "NVIDIA A100-SXM4-80GB" -> "nvidia_a100" "AMD Instinct MI300X" -> "amd_instinct_mi300x"
