功能修复: - 修复股票搜索功能: 'Info' object has no attribute 'search' 错误 - 使用本地股票列表实现搜索，支持代码和名称模糊匹配 - 搜索功能现在支持中文股票名称和股票代码搜索 配置优化: - 取消月线筛查: 从配置中移除monthly时间周期 - 更新默认时间周期: 仅保留daily和weekly - 提高扫描效率，专注于更及时的交易机会 技术改进: - 实现基于pandas的本地搜索算法 - 支持不区分大小写的模糊匹配 - 完善错误处理和日志记录 - 保持API兼容性 测试验证: - 搜索'平安'返回3个相关股票 - 支持按股票代码和名称搜索 - 错误处理机制正常工作 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
