…NPU buffer - Add examples/disagg_prefill/hccs: TP=1 PD example over HCCS only (no RoCE), using the hixl transfer channel with HCCS env vars. - Align the PD NPU transfer buffer to 2MB in the Ascend PD backend so HCCL/HIXL can register the buffer VA (errors 503900/507899 otherwise). Construct the PagedTensorMemoryAllocator directly from the aligned buffer to keep buffer/free_blocks consistent.
