fix: 修复编译错误和警告

Browse Source 
编译错误修复:
- 修复gemini_service.rs中response borrow错误
- 在使用response.text()前保存status值

 警告清理:
- 移除未使用的导入: std::collections::HashMap, uuid::Uuid, tokio::sync::Mutex
- 修复未使用变量警告: 添加下划线前缀
- 移除不必要的mut关键字

 编译状态:
- 所有编译错误已修复
- 仅保留1个合理的dead_code警告
- 代码质量显著提升

现在代码可以正常编译运行，准备测试AI分类功能。
