Gahow Wang cdf83493ab Fix A+C: real cache sync + cached-prefill-on-C architecture ...

A: Add /estimate_hit endpoint to bootstrap server for real-time cache
   probing. Proxy queries this before committing to PUSH, eliminating
   24% zero-match PUSH requests (shadow cache divergence).

C: Add _handle_cached_prefill_offload: C (cache source) does fast
   cached prefill → KV to Mooncake → D pulls and decodes.
   Replaces broken direct_read PUSH where D waited for RDMA transfer
   while occupying KV blocks without doing compute.

Also: update §3.9 baseline to plain vLLM with full mean/p50/p90/p99.
