debt(D7): 限流/KeyRing 单进程限制说明 + 生产启动一次性告警

- app.py lifespan:APP_ENV=production 时 logger.warning 提醒
  进程内 rate-limit/KeyRing 仅单进程有效(不 sys.exit、不引入 Redis)
- key_ring.py docstring 补充多 worker 不共享的后果说明
- deps.py 注释已具备(单进程有效,生产前置 Nginx),无需改动

+"""D2 工程债回归测试: 统一预测结果类型。
+
+背景: predict_match 三条路径返回类型不一 —— single 返回 PredictResult,
+multi 返回字段重复定义的 MultiPredictResult dataclass,baseline 返回裸 dict。
+后果: (1) 预测路由 PredictOut 映射被迫写 isinstance(result, dict) 双分支;
+(2) backtest 对 baseline 模式直接 AttributeError(dict 没有 .prediction_id,
+潜伏 bug);(3) 字段清单在两处 dataclass 重复维护,加字段必漏一处。
+
+统一方案: 扩展 PredictResult(可选字段)承载全部模式;
+MultiPredictResult 变为其别名(保留 orchestrator 签名标记,兼容 re-export);
+baseline 返回 PredictResult;路由单一字段映射。
+
+本测试守护四件事:
+  1. predict_baseline 返回 PredictResult(属性访问)
+  2. MultiPredictResult 与 PredictResult 兼容(orchestrator 构造调用的
+     全字段 kwargs 可直接构造别名)
+  3. 预测路由不再有 isinstance(result, dict) 分支(源码守卫,仿 R4 范式)
