Set up Cursor Cloud development environment

[JClemente-web]

Summary

Sets up the development environment for the "Sistema de Eventos Acessíveis" Spring Boot 4 + PostgreSQL REST API and verifies it end to end. Adds AGENTS.md documenting durable, non-obvious startup guidance for future cloud agents (PostgreSQL is required and does not auto-start).

No application code was modified.

Environment

• JDK 21, Maven 3.8.7, PostgreSQL 16 provisioned in the VM.
• Created database eventos_db and set the postgres password to match application.properties.
• Update script (dependency refresh only): mvn -B -q dependency:go-offline.

Verification

• Build: mvn -DskipTests clean compile — success.
• Tests: mvn test — 1/1 passing (@SpringBootTest context load, Hibernate schema created).
• Run: mvn spring-boot:run — app started on port 8081.
• Hello-world: created a participante via POST /participantes (HTTP 201) and listed via GET /participantes (HTTP 200), both through Swagger UI and curl.
