Hello PyTorch with the Job API

The maintained Hello PyTorch Job API walkthrough is now consolidated in Hello PyTorch. Its zero-argument simulation uses deterministic, independently generated synthetic data from one simple IID distribution, one local epoch per round, and final-global-model evaluation. CIFAR-10 is an explicit follow-up rather than a first-run dependency.

See the example README for the authoritative commands, options, artifacts, data contract, and limitations. For general concepts, see Client API and Available Recipes.
