ZacharyZcR 678d750c8a refactor: 重构插件架构,实现单文件插件系统
将复杂的三文件插件架构(connector/exploiter/plugin)重构为简化的单文件插件架构,
大幅减少代码重复和维护成本,提升插件开发效率。

主要改进:
• 将每个服务插件从3个文件简化为1个文件
• 删除过度设计的工厂模式、适配器模式等抽象层
• 消除plugins/services/、plugins/adapters/、plugins/base/复杂目录结构
• 实现直接的插件注册机制,提升系统简洁性
• 保持完全向后兼容,所有扫描功能和输出格式不变

重构统计:
• 删除文件:100+个复杂架构文件
• 新增文件:20个简化的单文件插件
• 代码减少:每个插件减少60-80%代码量
• 功能增强:所有插件包含完整扫描和利用功能

已重构插件: MySQL, SSH, Redis, MongoDB, PostgreSQL, MSSQL, Oracle,
Neo4j, Memcached, RabbitMQ, ActiveMQ, Cassandra, FTP, Kafka, LDAP,
Rsync, SMTP, SNMP, Telnet, VNC

验证通过: 新系统编译运行正常,所有插件功能验证通过
