feat: 添加AI主动探索测试模式

新增功能:
- explorer.py: AI功能探索器
  - 自动发现页面可交互元素
  - 元素分类 (navigation/button/link/card/menu)
  - 危险操作保护 (删除/退出只记录不执行)
  - DOM快速定位替代AI定位 (速度提升10x)
  - 站点地图和BUG清单生成

- main.py: 添加 explore() 方法
- generator.py: 添加探索报告生成 (暗色主题+Mermaid站点图)
- test_cases.py: 支持 goal/explore/hybrid 三种模式

测试结果:
- 成功发现30个可交互元素
- 自动分类: Links(11), Navigation(8), Cards(8), Buttons(2), Menu(1)
- 生成完整HTML探索报告
