Add Decky Clash to Plugin Store

DeckyClash is a light-weight Clash/Mihomo proxy client for Steam OS. Last submission is in #828 and all issue is solved.

What is Clash/Mihomo?

Clash is an open-source, rule-based proxy client that supports a wide variety of protocols like SOCKS5, HTTP, Shadowsocks, and VMess. It's widely used for advanced network routing, traffic splitting, and bypassing restrictions. However, the original Clash has been discontinued, and newer forks, e.g. Mihomo, have taken its place.

Mihomo depends on its configuration to work, which describes proxy server and instructs how traffic routes. Many popular proxy providers give user a URL to fetch latest configuration, but it's hard to maintain it manually, especially using Steam Deck.

In short, Clash/Mihomo is a network proxy tool, which can encrypt network traffic, bypass firewall and boost online gaming experience. And Decky Clash is a GUI wrapper of Mihomo for SteamOS users, providing many useful utilities.

Who need this?

It is really necessary for Chinese users, who are suffering from poor network connections to Steam and many other aboard gaming servers. Almost every Chinese Steam user uses proxy tool to boost their connection, while half of them are using Clash/Mihomo. Iranian and Russian users share some similar situation.

The reason why the network connections are poor for Chinese users:

• Valve has not officially entered China, but its bussiness is allowed to due to China's membership in the WTO.
• However, There is NO Steam CDN (except download) located in China subjected to compliance requirements.
• International network in China suffers from congestion.
• Censorship makes some network services unavailable.

What does this do?

This plugin provides an easy-to-use UI for SteamOS users to utilize Clash/Mihomo tool. What you can find in the screenshots is its useful UI, like subscription manager, etc.
