chore: merge CI stages into a single release job to optimize speed

Merge build, package, and deploy stages into a single 'release' job. By building
the jar and running docker commands in the same container using local docker socket,
we completely bypass the need for GitLab artifact uploading/downloading. This significantly
reduces network overhead and speeds up release deployment.
