This change introduces a custom Docker image for the PR CI workflow to significantly speed up build times by pre-installing expected Java versions (8, 17, 21) and caching large dependencies like cn1-binaries.

Changes:

  • Added .ci/container/Dockerfile: Defines the image with Ubuntu 24.04, JDKs (ZuluFX 8, OpenJDK 17/21), and cn1-binaries.
  • Added .github/workflows/build-container.yml: Workflow to build and push the image to GHCR.
  • Updated .github/workflows/pr.yml:
    • Uses the new container image for the build job.
    • Replaces actions/setup-java with fast environment switching for pre-installed JDKs.
    • Links pre-downloaded cn1-binaries instead of downloading them during the run.
    • Added packages: read permission to pull the container.

- Added `.ci/container/Dockerfile` to pre-install JDKs (8, 17, 21) and cache `cn1-binaries`.
- Added `.github/workflows/build-container.yml` to build and push the image to GHCR, ensuring the repository name is lowercased for valid Docker tags.
- Updated `.github/workflows/pr.yml` to run inside the new container, replacing `setup-java` with fast environment switching and linking pre-downloaded binaries.
- Fixed an issue where mixed-case repository names caused Docker build failures by enforcing lowercase tags in `build-container.yml` and using the canonical image name in `pr.yml`.
