fix: [CI-21185]: Start of Harness CI builds (#50)

This is a placeholder commit to enable Harness CI build pipeline.

Harness CI requires branch format 'release/*' for PATCH releases.
Command format: SERVICE_NAME@release/branch-name

All actual implementation for CI-21185 has been completed in previous PRs:
- #47: Dockerfile and versioning support
- #49: Helm chart for build pipeline compliance

This PR establishes the release branch for CI/CD integration.
