Adding prompts to the GT MCP server

The MCP server can generate prompts based on a given template.

Start the server:

server := GtLMcpServer new
		port: 3003;
		start

Add a prompt to it:

server
	addPrompt: (GtLMcpPrompt new
			name: 'Code Review';
			description: 'Asks the LLM to analyze code quality and suggest improvements';
			arguments: {'code'};
			promptBlock: [ :arguments | 
				{GtLAnthropicUserMessage new
						markdown: 'Review the following code as if you were a senior developer:
			
```
' , (arguments at: 'code')
											, '
```'} ])

Once we have the prompt, we can access it from the client. For example, we can set up a GT client:

client := GtLMcpClient new
	transport: (GtLMcpHttpTransport new url: 'http://localhost:3003/')

And create messages from it directly.

(client
	messagesFromPrompt: 'Code Review'
	withArguments: {'code' -> '(defn a-clojure-fn [x] (* x 2))'} asDictionary)
	first

Stop the server once you're done with it:

server stop
