增强版彩票智能分析系统 v2.0
===============================
核心升级：
  1. 采集近200期数据（原100期）
  2. AI逐期回滚推演：从第200期开始->模拟分析机选->比对实开->回滚优化
  3. 方法论自优化：每轮回滚后总结方法论并迭代升级
  4. 目标：胜出率(概率占比) >= 51%

用法:
  python enhanced_lottery.py --action full_report --lottery ssq --count 5
  python enhanced_lottery.py --action rollback --lottery ssq
  python enhanced_lottery.py --action self_evolve --lottery ssq --iterations 10
