ci: migrate to GitLab CI with multi-distribution RPM builds

- Replace GitHub Actions with GitLab CI using Docker-in-Docker
- Build 3 RPMs (el7, el8, el9) + 1 DEB from Dockerfile.package
- Add verify jobs for each target distribution
- Remove obsolete files:
  - Dockerfile, Dockerfile.test-socket (replaced by Dockerfile.package)
  - scripts/socket_consumer.py, scripts/socket_listener.py
  - scripts/test_unix_socket.sh, scripts/run_integration_tests.sh
- Update README.md with new package targets
- Update architecture.yml for GitLab CI workflow

Breaks: Single RPM no longer supported (glibc incompatibility)
Replaced by: Distribution-specific RPMs (el7, el8, el9)
