纯文件级移动，无行为变更，沿用既有的 fulfillment_<aspect>.go 命名约定： - fulfillment.go 结构体、构造函数、上游钩子、CanFulfill、orderCallbackData - fulfillment_create.go 下单类型定义、CreateManualOrder、CreateOrder - fulfillment_testorder.go 联调测试订单 - fulfillment_update.go 履约结果更新 - fulfillment_cancel.go 取消订单（含上游联动取消） 校验：拆分前后 19 个 func/type 声明完全一致（无缺失、无多出、无重复）。
