完成压力测试工具优化和文档整理

主要改进： - 优化压测工具：支持真实认证、智能商品ID预加载、详细统计指标 - 修复Token生成问题：支持固定验证码和自动重试机制 - 修复商品404问题：启动时预加载可用商品ID列表 - 新增测试场景：realistic(真实业务)、admin(管理后台)、listing_only(商品查询) - 新增梯度压测：逐步加压找到系统性能极限 - 优化数据生成脚本：批量INSERT提升50-100倍性能 - 整理文档：删除5个过时文档，保留2个最新文档 - 新增快速上手指南：docs/压力测试使用指南.md 性能基线(10并发)： - QPS: 2,600+ - P50/P95/P99延迟: 3ms/7ms/10ms Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
