feat(proxy): 安全加固与架构优化

- 引入 SafeDnsResolver 消除 DNS rebinding TOCTTOU 漏洞,DNS 缓存改为多地址存储
- 扩展私有 IP 检测范围(CGNAT 100.64/10、基准测试 198.18/15、保留 240/4)
- 请求处理增加 hop-by-hop 头过滤、URL scheme 校验、超时范围限制
- 动态配置从 RwLock 切换到 ArcSwap 实现无锁读取
- 启动注册失败的服务器支持后台自动重试
- WebSocket 帧大小上限提升至 64MiB 匹配 Python 端
- 心跳支持动态间隔更新,新增 failed_requests/dns_failures/stream_errors 指标
- 配置启动校验、systemd UMask=0077、配置文件权限 600
- Python 端支持 per-connection max_streams(X-Tunnel-Max-Streams)
