feat: add support for the new SDK server

This change introduces the fork/exec of the SDK server. Then all
operations are requests to that server. The starting and stopping of
this server is handled by creating/closing clients.

 ## Client
 
-There are currently a couple "global" options, and the client helps to manage those. A client without any options is
-likely what you want. However, here are the current global options:
-
-- `gptscriptURL`: The URL (including `http(s)://) of an "SDK server" to use instead of the fork/exec model.
-- `gptscriptBin`: The path to a `gptscript` binary to use instead of the bundled one.
+The client allows the caller to run gptscript files, tools, and other operations (see below). There are currently no options for this client, so calling `NewClient()` is all you need. Although, the intention is that a single client is all you need for the life of your application, you should call `Close()` on the client when you are done.
