Add a lightweight GitHub Actions check for all five Docker Compose configurations on pushes to main, pull requests, and manual runs. Restricting push checks to main avoids duplicate push and pull request runs for feature branches. Each file is validated with docker compose config --quiet using its matching env-example, so invalid YAML or Compose models fail CI without pulling images or starting containers. The workflow uses read-only repository permissions, and the README includes a local validation command.

Verification

• Parsed the workflow YAML and checked the validation script with bash -n.
• Ran the exact workflow script locally with an unavailable Docker daemon endpoint; all five configurations passed.
• git diff --check passed.
• Existing warnings about the obsolete version field and unset TLS_ENDPOINTS remain non-blocking.
• The updated workflow passed on GitHub Actions for the pull request.
