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)

version_parser_test.go - Banner清理与版本解析测试
测试目标:TrimBanner 函数
价值:Banner清理是服务识别的预处理步骤,错误会导致:
- 误识别服务类型
- 正则匹配失败
- 日志输出混乱(控制字符污染)
"Banner清理看起来简单,但涉及ASCII控制字符、Unicode、空格压缩。
这是真实的网络数据处理,必须测试边界情况。"
