AI Summary: Set up a Spring Boot application to create a REST API for registering ninjas and their missions. The API should handle ninja registration (name, age, email, rank) and mission registration (title, description). A ninja can be assigned to only one mission, but a mission can have multiple ninjas. The project uses Spring Data JPA, H2 Database, Flyway, and Maven. This initial task focuses on running the first program and verifying the basic Spring Boot setup.
