Add `--provenance=false` flag to `docker build` command. This stops Docker BuildKit
from generating OCI Referrers/attestations, which are not correctly parsed by GitLab
Container Registry and cause the UI to display 0B size and "missing manifest digest" errors.
Replace custom registry variables with GitLab's predefined CI_REGISTRY,
CI_REGISTRY_IMAGE, and CI_REGISTRY_USER to ensure the built-in CI_JOB_TOKEN
has correct push permissions.
Replace DinD services with unix:///var/run/docker.sock socket binding to
fix "Cannot connect to Docker daemon" errors. Add -PartefactVersion
parameter to Gradle build for release version tracking.
Replace the full CI pipeline (build → image → push → SSH deploy on every branch)
with a focused release workflow: build JAR on tag push, package Docker image
tagged with the release tag, and push to registry.onixbyte.cn.
