Push-based KV transfer to improve TTFT and TPOT for disaggregated inference in vLLM

What changed

vLLM introduces push-based KV transfer to improve time-to-first-token in disaggregated inference.

Why you should care

Push-based KV transfer removes sequential coordination steps from the critical path, potentially lowering TTFT.
