Go边缘代理: 单文件可执行+嵌入式MediaMTX+监控+注册

- edge-agent/: Go项目, 支持Windows托盘/Linux无头两种模式
- 使用go:embed将MediaMTX二进制嵌入单一可执行文件
- 首次运行自动释放MediaMTX并生成边缘节点配置
- 自动注册到origin (POST /api/nodes/register)
- 10秒心跳上报CPU/RAM/带宽/连接数 (gopsutil采集)
- Windows: getlantern/systray托盘菜单(状态/CPU/MEM/带宽/退出)
- Linux: headless模式,适合systemd守护
- build.sh/build.ps1: 交叉编译脚本(Linux/Windows)
- 更新start.sh/品牌名StreamCore
