feat: super evolution — 20 new security modules with full test coverage
新增20个超进化安全模块 (17 new services + 1 test suite + Dashboard API): - JWT认证服务 (JwtAuthService): 基于HMAC-SHA256的token管理 - 反暴力破解 (BruteForceProtectionService): 渐进延迟+三层时间窗口检测 - 反机器人检测 (AntiBotDetectionService): MC玩家名模式+加入速度+多账号检测 - 反向Shell检测 (ReverseShellDetectionService): 50+ reverse shell模式匹配 - ARP欺骗检测 (ARPSpoofDetectionService): MAC变更+网关欺骗+重复MAC检测 - DNS隧道检测 (DNSTunnelDetectionService): 熵值分析+子域名编码+频率监控 - 漏洞签名检测 (ExploitSignatureService): Log4Shell/SQL注入/XSS等15+签名 - SSRF防护 (SSRFProtectionService): 内网IP/云元数据/编码绕过检测 - XXE防护 (XXEProtectionService): XML实体注入+十亿笑攻击检测 - CSP强制执行 (CSPEnforcementService): XSS/Clickjack防御+安全响应头 - 数据库防火墙 (DatabaseFirewallService): SQL注入+危险关键字+堆叠查询检测 - 数据防泄漏 (DataLossPreventionService): 12种敏感数据模式(邮箱/API Key/SSH Key等) - 内存保护 (MemoryProtectionService): JVM堆监控+GC过载+内存泄漏检测 - 进程注入检测 (ProcessInjectionDetectionService): 线程异常+内存映射+文件描述符 - 安全文件删除 (SecureFileDeletionService): DoD多pass覆写+擦除后删除 - 取证收集器 (ForensicsCollectorService): 进程/网络/文件/日志取证 - 事件响应 (IncidentResponseService): 5套Playbook(DDOS/爆破/入侵/MC漏洞/数据泄露) - 威胁狩猎 (ThreatHuntingService): 10种主动狩猎规则 - 合规扫描 (ComplianceScannerService): 7大类20+项合规检查 - 反破坏检测 (AntiGriefDetectionService): MC方块破坏/放置/实体/容器监控 API端点: DashboardController新增20+个安全API端点 测试: 64个测试全部通过 (12 existing + 52 new)
