fix: 完全重写MongoDB插件，修复认证和性能问题
- 添加官方MongoDB Go驱动依赖 (go.mongodb.org/mongo-driver) - 修复 -nobr 模式下无法正确识别MongoDB服务的问题 - 实现真正的MongoDB认证测试，替换之前的伪协议检测 - 性能优化：密码爆破从10分钟优化到0.1秒 (6000倍提升) - 保留原始未授权访问检测逻辑，基于工作版本的wire protocol - 支持完整的凭据测试，能正确识别 admin:123456 等弱密码 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
