- Pin to eclipse-temurin:21.0.10_7-{jdk,jre}-noble for reproducible builds
- Switch -DskipTests to -Dmaven.test.skip=true: skips test compilation entirely,
not just execution — faster and avoids build failures from test-only missing classes
- Add comment on COPY *.jar explaining why the glob is safe (Spring Boot renames
the pre-repackage artifact to .jar.original, leaving only one .jar in target/)

Replace runtime mvn spring-boot:run with a proper multi-stage build:
- Stage 1 (builder): compiles JAR with BuildKit cache mount for ~/.m2
- Stage 2 (runtime): eclipse-temurin:21-jre with only the JAR
Removes the backend source volume mount and maven_cache named volume.
Deploy with: docker compose up -d --build

mvnw is a bash script; eclipse-temurin:21-jdk-alpine only provides ash
(busybox), causing the container to exit silently with code 0 before the
JVM starts. The Debian-based eclipse-temurin:21-jdk image includes bash.

Replace the devcontainer (sleep infinity + VS Code image) with a proper
dev setup:
- Dockerfile: eclipse-temurin:21-jdk-alpine running ./mvnw spring-boot:run
- Source mounted at /app, Maven deps cached in named volume maven_cache
- Healthcheck on /actuator/health so frontend waits until backend is ready
- frontend depends_on backend: service_healthy (was service_started)
