Add homebrew distribution

On MacOS Homebrew https://brew.sh is the defacto package manager to install Apps or CLIs.

Using npm for distributing the cli has some downsides

One I ran into today was that:

I use fnm to manage Node versions, which keeps multiple versions of Node and NPM and depending on the project needs it switches to the correct version using symlinks.

Since the cli is installed globally and the npm stores that in a folder scoped to a specific Node version, when I try to use the cli in a different repo which uses a different version of Node (and hence npm) the socket cli is not found.

With Homebrew distribution, the whole system gets the same socket cli version, unlike Node, Homebrew is installed system-wide and doesn't change per-project.

未指定文件、测试或入口点。首先检查现有的 npm 打包和发布配置，然后确定应在哪里集成 Homebrew 分发。完成的标准是 CLI 可以通过 Homebrew 在系统范围内安装，并且在项目使用不同 Node 版本时仍然可用；验证安装和调用路径。
