Hyperpod Version Checker

This script checks everything that matters: NVIDIA drivers, CUDA, cuDNN, NCCL, EFA, MPI, Neuron SDK for Trainium, and the usual Python/PyTorch stack. It's a bash script you upload via the hyperpod-ssm skill and run on each node, with JSON output that makes diffing across nodes straightforward. The real value is the compatibility analysis built in, like catching when your driver doesn't support your CUDA version or when NCCL versions aren't consistent. Saves you from debugging distributed training failures that turn out to be a version mismatch on node 7.
