- 迁移 000251~000254：运营商账户调度参数、请求检查场景（预置 8 个）、卡轮询失败告警表，以及调度模式、步骤、退避、告警等受控系统配置（默认 legacy，行为不变）；并发配置表注释标记废弃 - 受控系统配置注册与 JSON 结构校验：步骤只能是 4 种检查类型且不重复、退避序列递增 - yaml 增加 NSQ 地址、msg_timeout、租约、续期间隔、分发间隔、默认执行上限与 max_in_flight；引入 go-nsq - 测试环境 docker-compose 增加 nsqlookupd 与 nsqd，Worker 注入 NSQ 地址 - 账户队列 Redis 结构与 Lua：领取（执行上限、优先占比、按限流组剩余 QPS 估算）、抢执行权、续期、收尾、请求检查（合并、冷却、执行中打优先标记）、移出、发布失败释放
