定时爬取入口 —— 每天自动采集前一天的数据

使用方式:
  1. 直接运行（单次采集昨天数据）:
     python scheduler.py

  2. Windows 计划任务（每天早上 8:00 自动运行）:
     schtasks /create /tn "ZTB_Spider" /tr "python <项目路径>\scheduler.py" /sc daily /st 08:00

  3. Linux cron（每天早上 8:00）:
     0 8 * * * cd /path/to/ztb && python scheduler.py >> logs/cron.log 2>&1
