Gahow Wang bf037594c4 Production-realistic baseline: APC 67.5%, TPOT +139% from interference ...

Updated methodology:
- Window+thin sampling preserves cross-session sharing (48% vs 16%)
- --max-single-turn-ratio 0.3 boosts multi-turn to 70%
- --window-seconds 600 for 10-min contiguous window
- Trace-driven replay (no session limit, no time compression)
- Daily config: --requests 850 (~13 min, APC~76%)

Key result: TPOT p90=0.175s (vs 0.073s in legacy 1-req/GPU setup),
confirming prefill-decode interference is real at production concurrency.
APC 67.5% (vs 44%) from better KV reuse preservation.

Also fixed KV reuse breakdown: 62% intra-session / 38% cross-session
(was incorrectly reported as 91% / 9%).
