feat: npx create-ai-agent

[pkarw]

Let's add CLI for creating ai-agent:

• clone example
• setup package.json adding dependencies to fabrice-ai
• ask for OpenAI API Key,
• create a new empty agent

Future:

• prompt for what the agent is about to do and ... create the agent using fabrice-ai itself :D

Unfortunately, the name is taken.

We don't have empty template (we should create one in examples/ folder, then, add it to the CLI and it will just work). We also don't ask for the OpenAI key, which we should do!

I'll send a follow-up if I have enough time later today!

We should also pick the right dependencies that the template uses, so we need to add additional object: "dependencies" per each dependency, with versions, and append that to package.json manually, instead of copying the example/package.json.
