HF's one-week dual drop: 🤗 Kernels revamp (trust + cosign) and LeRobot v0.6.0 (world models + Robometer)

Hugging Face shipped two toolchain-level updates on consecutive days: July 6 saw the 🤗 Kernels revamp with trusted kernel publishers, Sigstore cosign signing, Torch Stable ABI support, and the first non-Torch framework (Apache TVM FFI). July 7 shipped LeRobot v0.6.0, introducing VLA-JEPA / LingBot-VA / FastWAM world-model policies, a unified Robometer reward model, and six new simulation benchmarks. Two products — one for inference/compile time, one for embodied learning — but released in the same week signals HF's strategy: 'move the infrastructure and the training paradigm together.'
