Create Spring Boot Java Project

Bootstraps a production-ready Spring Boot project with PostgreSQL, Redis, and MongoDB already wired up. Downloads the skeleton from Spring Initializr, adds SpringDoc for API docs, ArchUnit for architecture testing, and creates a docker-compose.yaml with all three databases configured. The configuration files include connection strings, JPA settings, and a .gitignore that excludes data directories. You'll have a running project in under two minutes instead of spending 20 minutes setting up dependencies and Docker services. Good for when you need to start a new microservice or prototype without the usual configuration headaches.
