Subject: [PATCH] feat: add build version injection via CI_COMMIT argument

Inject the build version into the binary using the CI_COMMIT
argument for better traceability of deployments. Update the
Dockerfile to pass the commit hash to the build process,
ensuring that each build contains version information tied
to the specific commit.
