- Created docker-compose.coolify.yaml for service orchestration with app, workers, MariaDB, and Redis.
- Introduced entrypoint.sh for initialization tasks like JWT key generation and database migrations.
- Configured Nginx with default.conf for handling requests and routing to PHP-FPM.
- Added php.ini with production settings and opcache configuration.
- Set up supervisord.conf to manage PHP-FPM and Nginx processes.
- Created frontend-domains.json for managing allowed frontend domains.
- Added gen-cors-env.php script to generate CORS environment variables from frontend domains.
- Updated framework.yaml to configure trusted proxies and headers.
