Migrating GitHub CI to Hugging Face Jobs

将 GitHub CI 迁移到 Hugging Face Jobs

Hugging Face describes using huggingface/jobs-actions to run GitHub Actions CI as HF Jobs, where the Trackio project cut CPU job time by about 30% and added a GPU test suite using CPU, t4-small, or h200 hardware.

Why it matters: HKR-H/K/R pass via a concrete CI-to-HF Jobs workflow, ~30% speedup, and GPU-test pain point. Scope is ML tooling, not a major platform release, so it sits at the featured threshold.
