被控端 - 修复 MTU 问题：夹 MSS + 路径 MTU 探测（公网可用率 48% -> 100%） - 复用 HTTP 连接（免掉每次新建 TLS 的 30% 握手失败） - 每分钟回头找局域网，自动切回快 400 倍的路径 - 画面心跳帧：静止时省流量，客户端仍知道流是活的 - 锁屏时给出可操作的提示 手表端 - 内置 GTS Root R4 / GlobalSign Root CA，修 SSLHandshakeException - 连接错误翻译成人话（证书/时间/解析/超时分别提示） - 经中转连上后用服务器报的地址刷新已配对记录 - 新增局域网连接页面、服务器延迟检测 服务器端 - 支持 chunked 请求体（修每 16 秒一次的连接错乱与大面积 502） - 网络调优脚本 net-tune.sh（开机自动应用） - 管理页：批量删除、网络体检、下载区 - 隧道改 HTTP/2 + 双连接 文档 - 许可协议 / 安装前必读 / 安装后须知（作者：小麦子）

"""把隧道看门狗写进 install.sh。
|
|
|
|
为什么需要：
|
|
匿名隧道在这条线路上时好时坏。tunnel-run.sh 只管**建立**阶段，
|
|
建立之后中途失效没人管 —— 用户只能自己发现、自己 SSH 上来重启。
|
|
看门狗每 5 分钟检查一次公网可达性，连续 3 次不通就重启隧道。
|
|
|
|
写进 install.sh 之后，别人部署也会有这个能力。
