Need More Protocols for Frontend.

Currently ZeroNet Supports websocket and html rendering, while on web these are sufficient, for native apps(apps which are not run on browsers), these are less efficient, suppose if you want to connect to site you need to render the site to get wrapper key and connect to websocket and get content from the site.
Instead I propose to add protocols like REST Api, which can also be used on browser side as well as native side. Further, unless you need real-time updates websocket is less efficient than REST API, since it need to persist connection between client and server.

未指定文件、测试或入口点。首先定位现有的 websocket 和 HTML-rendering 路径，然后与维护者明确 REST API 的范围以及原生/浏览器兼容性。完成的要求是先就端点和验收标准达成一致，随后实现协议。
