/**
 * Amazon SP-API 数据采集调度器（新版）
 *
 * 相较旧版 sp-api-schedule.ts，本版将四个采集步骤拆分为独立的公共方法：
 *   - collectListings   采集 Listing 数据
 *   - collectOrders     采集订单数据
 *   - collectReports    采集报表数据
 *   - parseReports      解析/检查未完成报表
 *
 * 每个方法均接受可选的 ProgressCallback，适合通过 SSE 向前端推送实时进度。
 * 定时任务（每天凌晨 1 点）调用上述方法时不传 callback，仅打印日志。
 *
 * 使用方式：
 *   import { newSpApiScheduler } from './new-sp-api-schedule.ts';
 *   // 仅手动触发，不启动 cron（由旧版 spApiScheduler 维护 cron）
 *   await newSpApiScheduler.collectListings(shopId, progressCallback);
