ci: remove isolated GLB release check

[nerdalert]

Summary

• remove the GLB-only Forge configuration check from the release publication workflow
• keep topology runtime qualifications in the pre-release validation process
• avoid treating one experimental topology as a special artifact-publication gate

Validation

• actionlint .github/workflows/release.yaml
• git diff --check

This does not change the existing v0.1.4 tag or its active release workflow run.
