由于ebpf程序已经加载，但group还没有ready，这时解析节点域名的数据包将不可能发出
会卡很久直到超时失败后打印日志，此时如果有其他可用节点则可以继续启动
此外，如果在此问题发生时通过 systemctl stop dae 停止dae，dae不会删除已经加载的bpf程序

相关代码：https://github.com/daeuniverse/outbound/blob/d470a59233a522657f8af39c7e44e2d56cdec3ac/protocol/hysteria2/dialer.go#L26

Expected Behavior

在加载bpf程序前解析节点

Steps to Reproduce

绑定 wan_interface
使用通过域名连接的hysteria2节点
启动 dae

原因未知，但似乎已无法在最新 main 分支复现
