Create initial repository scaffold

[dollarop]

This PR initializes the repository with a clean scaffold for legal AI-assisted earning workflows.

Key additions:

• .gitignore: Configured to prevent accidental leaks of sensitive data (tokens, secrets, private keys, personal profiles).
• AGENTS.md: Defines ethical and security boundaries for AI agents.
• README.md: Explains the repository's focus on public artifacts.
• Directory Structure: Established the core folders with .gitkeep to maintain structure.

The setup ensures a safe and transparent environment for public AI work artifacts.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!
