chore: 移除 fscan-lite (C 版本)

功能过于单一（仅 TCP 端口扫描），与 fscan 品牌定位不符。 fscan-nolocal 已是精简版的正确方案。 - 删除 fscan-lite 源码和构建脚本 - goreleaser 移除 lite 构建步骤 - CI 不再安装 mingw 交叉编译工具

-# fscan-lite
-
-极简但极致兼容的TCP内网端口扫描器
-
-## 设计理念
-
-**兼容性第一，简洁至上**
-
- 支持从 Windows 98 到 Windows 11
- 支持从 Ubuntu 8.04 到最新版本  
- 使用 C89 标准，最大兼容性
- 静态编译，零依赖运行
- 单个可执行文件 < 1MB
-
-## 功能特性
-
- ✅ TCP端口连接扫描
- ✅ 支持端口范围 (1-65535, 80,443)
- ✅ 可配置超时时间
- ✅ 静态编译，零依赖
- ✅ 跨平台兼容
-
-## 编译
-
-### Linux/Unix
-
-```bash
-# 动态编译
-make
-
-# 静态编译（推荐）
-make static
-
-# 最小化编译
-make small
-```
-
-### Windows
-
-```bash
-# MinGW 编译
-mingw32-make -f Makefile
-
-# 或使用MSVC
-cl /TC src/*.c /Febin/fscan-lite.exe ws2_32.lib
-```
-
-## 使用方法
-
-```bash
-# 基本用法
-./bin/fscan-lite -h 192.168.1.1 -p 22,80,443
-
-# 扫描端口范围
-./bin/fscan-lite -h 10.0.0.1 -p 1-1000
-
-# 自定义超时
-./bin/fscan-lite -h 192.168.1.100 -p 80,443 -t 2
-```
-
-## 参数说明
-
-| 参数 | 说明 | 示例 |
-|------|------|------|

-| --version | 显示版本 | --version |
-
-## 二进制大小对比
-
-| 版本 | 大小 | 说明 |
-|------|------|------|
-| fscan (Go) | ~30MB | 包含运行时 |
-| fscan-lite | ~900KB | 静态编译 |
-| fscan-lite (strip) | ~700KB | 去除调试信息 |
-
-## 兼容性测试
-
-### Linux 发行版
- ✅ Ubuntu 8.04 - 24.04

- ✅ Windows 98 SE
- ✅ Windows XP
- ✅ Windows 7/8/10/11
- ✅ Windows Server 2003-2022
-
-## 技术实现
-
- **语言**: C89 (最大兼容性)
- **网络**: 原生socket API
- **编译**: GCC/MSVC/Clang
- **链接**: 静态链接，零依赖
- **大小**: < 1MB 单文件
-
-## 性能对比
-
-| 指标 | fscan | fscan-lite |
-|------|-------|------------|
-| 启动时间 | ~50ms | ~5ms |
-| 内存占用 | ~20MB | ~2MB |
-| 扫描速度 | 1000 ports/s | 1000 ports/s |
-| 兼容性 | 现代系统 | 25年跨度 |
-
-## 构建配置
-
-```bash
-# 查看构建信息
-make info
-
-# 所有构建选项
-make help
-```
-
-## 许可证
-
-与 fscan 主项目保持一致
-
