Implemented a new 'simple onboard' command that provides a comprehensive, interactive wizard for new users. This wizard guides users through the 6 core pillars of the platform: Environment Check, Company Context Setup, Framework Integration (simulated), SOP Execution, Ghost Mode Activation, HR Loop Demonstration, and Operational Dashboard Launch. Includes updated documentation and robust integration tests mocking all external dependencies.

👋 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!
