Hugging Face CLI renamed to hf with reorganized commands and migration guidance

AI Impact Summary

Hugging Face has renamed the CLI from huggingface-cli to hf and reorganized commands into a consistent hf <resource> <action> structure. This improves ergonomics for developers and sets the stage for future features by consolidating authentication, cache, repo, and jobs under clear namespaces. The change centers on the huggingface_hub tooling and introduces the new hf jobs service; the legacy huggingface-cli remains functional but will warn users to switch, guiding automation to hf equivalents like hf auth login and hf jobs run. Migration steps: upgrade huggingface_hub to the latest (pip install -U huggingface_hub), reload shells, verify with hf version and hf --help, and refactor scripts to use hf auth login, hf jobs run, etc.
