Gahow Wang 67fcec7933 Unified-routing A+B ablation: decode-aware LMetric + v3 anti-hotspot ...

cache_aware_proxy: add lmetric_decode_weight (decode-load penalty in the
LMetric fallback score) and a v3 anti-hotspot recent-migration penalty
(effective_load = num_req + recent-migration count over a sliding window),
preventing back-to-back migration clustering. UNIFIED_ABLATION.md documents
the A (overload_factor=1.3) + B' (decode-weight, max(num_req,1)) + RaceFix
sweep: A+B'+RaceFix reaches TTFT p90 7770ms, beating v3 PD-sep migration by
~20%. Runners/analyzer for the b3 trace replay included.
