- Add packages/containers/jetbrains/Dockerfile extending bun-node with
Java 21 (apt-get, multi-arch safe) and Gradle 9.4.1 pre-cached in
GRADLE_USER_HOME so the wrapper skips the network download
- Register the new image in build.ts (after bun-node, before rust) and
update README
- Fix containers.yml branch trigger: dev → main so images are actually
published from the default branch on every relevant push
