[Feature] Add the `/connect` path

[pi314ever]

Currently in order to authenticate, we need to launch opencode externally. It would be great if we could authenticate within the neovim instance without launching another opencode. Not sure if this path exists via the server API though.

It sounds like a somewhat strange request, so would you possibly use opencode.nvim without using opencode-tui at all?

@pi314ever Is this something you're interested in?

@jensenojs I've transitioned to using nickjvandyke/opencode.nvim flow since it fits my workflow better.
