Improve store screenshots with automated pipeline

[lestephen]

Current State

We have manual screenshot generation scripts:

• scripts/generate-screenshots.js - Node.js script for automated capture
• scripts/generate-screenshots.sh - Shell wrapper
• SCREENSHOT_CHECKLIST.md - Manual capture guide

Goals

Evaluate and potentially implement a more robust screenshot automation pipeline:

• Evaluate fastlane snapshot for iOS-style screenshot automation
• Consider multiple language support for localized screenshots
• Ensure consistent quality across light/dark themes
• Automate screenshot generation as part of CI/CD
• Support both Windows and macOS store requirements

Considerations

• Current scripts work but are somewhat manual
• Store requirements differ between Microsoft Store and Mac App Store
• Screenshots need to be updated for each release with UI changes
