📜 Scribe: Updated Technical ARCHITECTURE.md

[google-labs-jules]

🔄 Drift Detected: A new cross-platform desktop worker (Flutter) for macOS/Windows was introduced in worker_flutter/, which bypasses the HTTP polling queue system and uses the Cloud Firestore SDK directly, but ARCHITECTURE.md only documented the Node.js/Docker CLI worker.
📄 Docs Updated: [docs/ARCHITECTURE.md]
💎 Note for Showcase: The ARCHITECTURE.md file was updated to reflect the new worker structure. No new files were created, so no changes are needed for the Documentation Map in README.md.

👋 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!
