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
