用户早上撞上 Cloudflare Error 1033。查出来是设备**掉电重启**：
上次开机到重启之间没有任何日志落盘（直接断电的特征），
dmesg 里还有 "l13: voltage operation not allowed"。
重启本身不是软件问题，但**恢复太慢**：
Startup finished in 3.846s (kernel) + 2min 6.358s (userspace) = 2分10秒
那 2 分钟里浏览器看到的就是 1033。
根因：
这台机器 NetworkManager 和 systemd-networkd 同时在跑，
但 wlan0 归 NetworkManager 管。
NetworkManager-wait-online -> 开机 9 秒成功
systemd-networkd-wait-online -> 等一个不归它管的网络，
干等 2 分钟超时，然后 failed
network-online.target 要等**两个都完成**，
被那个失败的拖了整整 2 分钟，
relay / tunnel / net-tune 全跟着等。
修法：
1. mask 掉 systemd-networkd-wait-online（网络不归它管，只会拖后腿）
2. watchdog 首次检查从"开机后 2 分钟"提前到 45 秒
实测（重启验证过）：
修之前 Startup finished in 3.846s + 2min 6.358s = 2分10秒
修之后 Startup finished in 3.218s + 14.060s = 17.3秒
掉电重启后公网恢复时间：**24 秒**（快了 5 倍多）
配套加了 scripts/speed-up-boot.sh，换设备时直接跑一遍。
顺带确认重启后一切自动恢复：
