FEAT: Add HackAPromptTarget for red teaming HackAPrompt challenges

[KutalVolkan]

Overview

This PR introduces a new target for automated red teaming and research on the HackAPrompt challenge platform.

How it works

• Log in to HackAPrompt, extract your session cookies, and configure your session ID and competition/challenge.
• The target sends your attack prompt, receives and reconstructs the model's response, and submits for judging to evaluate success.
• All feedback is displayed in the script output for easy red team iteration.

Challenge selection

Challenge selection uses a Python enum that maps the challenge_slug (required for the API), display name, and description.
Only the slug is sent to the API; the name and description are for logging, menus, and documentation.
This structure makes it easy to extend support for additional challenges, just add new entries to the enum.

How to run the demo

You can run the demo by executing:

python doc/code/targets/run_hack_a_prompt_target.py

Be sure to fill in your session info and cookies as described in the example script.

Note: I plan to extend support for more HackAPrompt challenges by adding their slugs and metadata to the enum in the coming days. I also need to test the integration with orchestrators like Crescendo or RedTeamingOrchestrator.

Hello Roman,

My holidays have started! 🙌 I’ll work on it tomorrow and make sure it’s ready to go, or at least ready for serious review 😁.
