  Chunking Qwen3.5's gated DeltaNet for 1.5x faster prefill on Apple Silicon

  Qwen3.5's hybrid layers replace attention with a gated delta rule, a sequential state update torch.compile cannot run fast. How Alloy maps it onto Metal: one serial kernel for decode, and a two-stage chunked kernel that makes prefill 1.5x faster at production depth.
