Support installing using Homebrew

[tha2015]

I need to run it locally (without using Docker), but it requires me to install Rust compiler and compile source code.

It would be great if we can just install it using a single command similar to
brew install github-mcp-server
( https://formulae.brew.sh/formula/github-mcp-server )
See https://github.com/Homebrew/homebrew-core/blob/main/Formula/g/github-mcp-server.rb for a similar formula

Adding to various software registries is something we'd like to do eventually, but in the meantime you can download binaries for your platform from the release page. We're still working on getting the Linux arm64 binaries added (see #156) but all the other binaries are available there. Just download the file, make it executable and move it to a directory in your PATH.
