hq450/fancyss ? reverse-engineered prompt

Build me a router plugin for Asuswrt and Merlin routers that makes it easy to get around blocked websites.

I want a simple web interface in the router admin page where I can add proxy nodes by pasting a link, typing them in manually, or importing a subscription. It should support common node types like Shadowsocks, SSR, Vmess, Vless, Trojan, NaiveProxy, and Xray or V2Ray JSON configs.

Please include easy ways to switch between proxy modes like global, game, mainland only, and routing only selected devices through the proxy. It should also handle DNS splitting, IPv4 and IPv6, UDP and TCP traffic, and let me block QUIC if needed. I’d like basic tools too, like checking if a node is alive, testing latency, auto updating subscriptions and rules, and showing the current status clearly.

Make it work for supported Asus routers and keep it installable from the router software center. If you need current docs, look them up online.
