fix(gamma): historySamples from store.stats() — unlock cold start at 7806 records 根因: createReasoningEngine({ store }) 没传 historySamples → opts.historySamples ?? 0 → 永远 0 → 永远 cold start (0 < 100 threshold)
修复: http_bridge.mjs 启动时从 store.stats().total 读取历史总量 → 传入 engine
效果: gamma_history 从 0.55 (cold start) → 0.75 (热启动), is_cold_start → false
权重表切换: WEIGHTS_COLD{a:0.4,b:0.35,c:0.05,d:0.2} → WEIGHTS_DEFAULT{a:0.3,b:0.25,c:0.25,d:0.2}
     ↑ C(历史基率) 权重从 0.05 升到 0.25 ← 之前几乎忽略历史证据
