V5.0 Paper插件架构：深度植入Minecraft服务器进程，实现完美实时防护
核心变更： - 新增 PaperMC 插件层（14个新文件）：主插件入口 AluerPlugin + 10个 Bukkit 事件监听器 + DataBridge 数据桥接 + InternalCommandExecutor 内部命令执行器 - 运行时注入服务器进程，直接访问 Bukkit/Paper API，取消 RCON 中间层 - 9种反作弊实时检测（Speed/Fly/Jesus/NoFall/KillAura/Reach/AutoClicker/Scaffold/Nuker）全部迁移为事件驱动 - 聊天安全（刷屏/广告/钓鱼）与命令滥用检测由 AsyncPlayerChatEvent/PlayerCommandPreprocessEvent 直接拦截 - AlertType 枚举扩展至 47 项告警类型，覆盖反作弊/玩家行为/服务器保护/聊天安全/网络/主机全部维度 - 双模式兼容：serverguard.mode=plugin（嵌入式）| external（传统外部监控），旧模式代码完整保留 - Maven 构建切换为 shade 插件，生成 Paper 插件兼容的扁平 JAR - 278 项全量测试通过，0 失败
