DeepSeek V4

• Base model support (#41006).
• Multi-stream pre-attention GEMM (#41061), configurable pre-attn GEMM knob (#41443), and tuned default VLLM_MULTI_STREAM_GEMM_TOKEN_THRESHOLD (#41526).
• BF16 and MXFP8 all-to-all support for FlashInfer one-sided communication (#40960).
• PTX cvt instruction for faster FP32->FP4 conversion (#41015).
• Integrated tile kernels (head_compute_mix_kernel) for optimized head computation (#41255).
• Guard megamoe flag with Pure TP (#41522).
• Fixed persistent topk cooperative deadlock at TopK=1024 (#41189) and inter-CTA init race on RadixRowState (#41444), with temporary disable of persistent topk as a workaround (#41442).
• Fixed import error due to AOT compile cache loading (#41090).
• Fixed torch inductor error (#41135).
• Fixed repeated RoPE cache initialization (#41148).
• Fixed missing type conversion for non-streaming tool calls in DSV3.2/V4 (#41198).

Bug Fixes

• Fixed max_num_batched_token not being captured in CUDA graph (#40734).
• Fixed num_gpu_blocks_override not accounted for in max_model_len checks (#41069).
• Auto-disable expandable_segments around cumem memory pool (#40812).
• Fixed BailingMoE linear layer (#40859) and MLA RoPE rotation for BailingMoE V2.5 (#41185).
• Fixed reasoning parser kwargs not being passed to structured output (#41199).
