docs: recursively generate architectural READMEs for full repository transparency

[beginwebdev2002]

• Analyzes all source directories excluding node_modules, build outputs, and temporary files.
• Generates localized README.md files for each directory containing contextual emojis, Mermaid.js hierarchy diagrams, markdown tables describing file types and responsibilities, FSD indicators, dependencies lists, and usage snippets.
• Fixes documentation inconsistencies across backend and frontend workspaces and complies with 'Luxury Professional' tone requirements.
• Addressed code review feedback by removing temporary logging and test execution artifacts generated during the script execution.

👋 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!
