- Updated `.releaserc.json` to reflect changes in release command execution.
- Modified CI workflow to streamline the release process, including tagging and Docker image publishing.
- Removed obsolete publish workflow and integrated its functionality into the main CI workflow.
- Enhanced documentation to clarify the new release process and CI pipeline structure.
