- 新增 RoutingCache 组件，使用 sync.Map 缓存 Provider 和 Model - 新增 StatsBuffer 组件，使用 sync.Map + atomic.Int64 缓冲统计数据 - 扩展 StatsRepository.BatchUpdate 支持批量增量更新 - 改造 RoutingService/StatsService/ProviderService/ModelService 集成缓存 - 更新 usage-statistics spec，新增 routing-cache 和 stats-buffer spec - 新增单元测试覆盖缓存命中/失效/并发场景
