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）

"""给所有按钮加回退（撤销）。
|
||
|
||
用户原话："你直接给所有按钮都做一个回退功能不就行了吗"
|
||
|
||
设计
|
||
----
|
||
`run()` 执行完之后，**自动判断这一步能不能退、怎么退**，能退就记一条。
|
||
|
||
* 开关类（15 个） -> 翻回原值
|
||
* 画面类（15 个） -> 关掉画面（复用已有的 close_visuals）
|
||
* 撤不回来的 -> **不记**
|
||
|
||
最后一条很重要：关机、重启、删文件、结束进程这类记了只会给用户
|
||
"我还能退回去"的错觉，反而危险。所以专门列了个 IRREVERSIBLE 集合。
|
||
|
||
新增三个功能：
|
||
undo_last 回退上一步
|
||
undo_all 全部回退（倒序一条条撤）
|
||
undo_list 看还能回退什么
