feat: 站点适配器 FlareSolverr 集成 + 并发搜索优化

- site_adapter.go: SiteConfig 扩展 UserAgent/Timeout/Extra/FlareSolverrURL 字段 - site_adapter.go: doRequest() GET 请求支持 FlareSolverr 代理绕过 Cloudflare/WAF - site_adapter.go: buildRequest() 使用 cfg.UserAgent（覆盖默认 UA） - site_adapter.go: MTeam api_key 认证改为 Authorization: Bearer 格式 - site_adapter.go: 修复 2 个 go vet 冗余 StatusFound 警告 - site.go: Search() 重构为 sync.WaitGroup 并发执行，提升多站搜索性能 - site.go: siteModelToConfig() 改为 SiteService 方法，按 BrowserEmulation 填充 FlareSolverrURL - site.go: Search() 空关键词返回 [] 而非 error，nil slice 防护 - 新增 system_handler.go: 系统工具探测接口 - 新增 ffmpeg_auto_install.go: FFmpeg 自动安装服务 - 新增 scripts/install-ffmpeg.ps1: Windows FFmpeg 安装脚本
