chore: create production-v2 branch with content only

This branch contains ONLY:
- Pages (config/www/user/pages/)
- Themes (config/www/user/themes/)
- Plugins (config/www/user/plugins/)
- PRODUCTION.md
- Minimal .gitignore

Clean slate for production deployment.
All development files, configs, scripts removed.
