ctest: Qwen3-8B DFlash speculator — FP8 hidden-states ablation (bf16)

Test checkpoint — not a production release. Trained to validate the FP8-quantized hidden-states transfer backend added in vllm-project/speculators#1028 (draft, reviving #491).

Verifier: Qwen/Qwen3-8B
Algorithm: dflash
Hidden-states precision during training: bf16 (existing bf16 file backend)
Training data: 5K magpie + 5K ultrachat samples from inference-optimization/Dataset-Qwen3-235B-Instruct

This is one of a matched pair (...-fp8ablation-bf16 / ...-fp8ablation-fp8) trained identically except for the hidden-states transfer precision, to isolate the effect of FP8 quantization on speculator quality. See the sibling repo for the other precision.
