feat: v2.1.0 核心重构与功能增强

## 架构重构 - 全局变量消除，迁移至 Config/State 对象 - SMB 插件融合（smb/smb2/smbghost/smbinfo） - 服务探测重构，实现 Nmap 风格 fallback 机制 - 输出系统重构，TXT 实时刷盘 + 双写机制 - i18n 框架升级至 go-i18n ## 性能优化 - 正则表达式预编译 - 内存优化 map[string]struct{} - 并发指纹匹配 - SOCKS5 连接复用 - 滑动窗口调度 + 自适应线程池 ## 新功能 - Web 管理界面 - 多格式 POC 适配（xray/afrog） - 增强指纹库（3139条） - Favicon hash 指纹识别 - 插件选择性编译（Build Tags） - fscan-lab 靶场环境 - 默认端口扩展（62→133） ## 构建系统 - 添加 no_local tag 支持排除本地插件 - 多版本构建：fscan/fscan-nolocal/fscan-web - CI 添加 snapshot 模式支持仅测试构建 ## Bug 修复 - 修复 120+ 个问题，包括 RDP panic、批量扫描漏报、 JSON 输出格式、Redis 检测、Context 超时等 ## 测试增强 - 单元测试覆盖率 74-100% - 并发安全测试 - 集成测试（Web/端口/服务/SSH/ICMP）
