TRL FIXES MULTIMODAL LOGGING AND QUANTIZATION CRASHES ACROSS GRPO AND QORA PIPELINES

TRL shipped four critical fixes overnight for multimodal RL training, including a QLoRA + FSDP1 dtype crash that was breaking mixed-precision setups.

The biggest one: QLoRA + FSDP1 mixed-dtype configurations were crashing in prepare_peft_model, and that's now fixed [1]. Parallel to that, the multimodal logging system got a new control lever with the `log_multimodal` parameter added to both GRPOConfig and RLOOConfig [2], letting you silence image logging when you need lighter checkpoints. GKD also got a vocab_size validation fix for multimodal models [3] that was silently breaking configs that looked valid. On the data side, GRPO and RLOO now handle IterableDataset errors correctly instead of swallowing them [4]. Kernels desk shipped Helion support [5], enabling pure-Python Triton kernels to build as noarch variants, which means one binary for all torch versions. huggingface.js fixed their Deno e2e CI by setting minimumDependencyAge to 0 for local registry testing [6], unblocking the test pipeline.
