ykxmz 1.5.0：修复手表端 TLS 证书校验 + MTU 修复网络稳定性
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）

"""被控端改用**复用连接**做长轮询 —— 这是稳定性问题的真正解法。
|
||||
|
||||
实测证据（真机 192.168.10.105）：
|
||||
A) 每个请求新建连接（现状） : 约 70% 可用
|
||||
C) 一条连接连打 10 次 : 10/10 = 100%
|
||||
D) 直连本地 relay（对照） : 20/20 = 100%
|
||||
G) 到 1.1.1.1 的丢包率 : 40%
|
||||
E) 经隧道单次请求耗时 : 1.2 ~ 2.5 秒
|
||||
|
||||
结论：
|
||||
链路丢包 40%，**每次新建 TLS 连接有约 30% 概率失败**；
|
||||
但只要连接建起来，之后就能一直用（TCP 自己会重传）。
|
||||
而 RelayLink._post() 用的是 urllib.request.urlopen —— 每次都新建，
|
||||
等于白白扔掉 30% 的成功率。
|
||||
|
||||
改法：
|
||||
用 http.client.HTTP(S)Connection 复用一条连接。
|
||||
请求失败（连接断了）就关掉重开一次再试；
|
||||
重试仍失败才当真的失败 —— 这样短抖动也能自己扛过去。
