Replace texlive-full with the texlive packages the paper actually needs
(latexmk, latex-extra, pictures for TikZ, bibtex-extra, recommended
fonts), and use Ubuntu's valgrind instead of building 3.22 from source
- the distro version is newer now. Cuts the image by several GB and
removes the slowest step of the image build.
apt.llvm.org has no repository for the current ubuntu:rolling release,
and nothing pins clang 20 - CC=clang already resolved to the distro
clang. Drop the llvm.sh step along with its helper packages.
docker build now runs under the buildx docker-container driver, which
keeps the result in the build cache unless told otherwise, so push
directly from the build instead of tagging locally.
Replace the Jenkinsfile with .gitea/workflows/ci.yml. The CI image is
built from the Dockerfile and pushed to the Gitea container registry,
rebuilt only when the Dockerfile or pre-commit config changes. The
aarch64 release build now runs natively on an arm64 runner instead of
cross-compiling, so the cross toolchain and qemu are dropped from the
image. Artifacts still go to MinIO (via mc, skipped gracefully if
credentials are not configured); ccache uses actions/cache instead of a
host volume.
