Verbose Output

As you debug and build your AI agent, you'll probably want to dump a lot more context into the console... but at the same time, we don't want to make the user experience of our CLI tool too noisy...

Let's add an optional command-line flag, --verbose, that will allow us to toggle "verbose" output on and off. When we want to see more info, we'll just turn that bad boy on.

Assignment

Add a new optional command-line argument, --verbose. argparse makes this easy – "store_true" means the argument will be parsed as a boolean value of True if the flag is set, otherwise False. The optional argument can appear either before or after the prompt, and its variable will be accessible as args.verbose (assuming you named your parsed arguments args).
```
parser.add_argument("--verbose", action="store_true", help="Enable verbose output")
```
If the --verbose flag is included, the console output should include:
1. The user's prompt: "User prompt: {user_prompt}"
2. The number of prompt tokens: "Prompt tokens: {prompt_tokens}"
3. The number of response tokens: "Response tokens: {response_tokens}"
Otherwise, this metadata should not be printed – only the response.

Try running your script with and without the --verbose flag to verify the difference in output, e.g.,

uv run main.py "What is the meaning of life?" --verbose

uv run main.py "How much wood would a woodchuck chuck if a woodchuck could chuck wood?"

If everything looks good, run and submit the CLI tests.
