chore: Add automated release workflow and version management

- Add GitHub Actions workflow for automated releases
- Add semantic versioning support
- Update docker-compose files with version variables
- Add release script for manual versioning
- Add comprehensive version workflow documentation

🚀 Ready for v1.2.5 release
