Include CLI command for seeing your rate limit

const response = await fetch('https://openrouter.ai/api/v1/auth/key', {
  method: 'GET',
  headers: {
    Authorization: 'Bearer <OPENROUTER_API_KEY>',
  },
});

I'll build this as llm openrouter key-info.

llm openrouter key-info
