Remove CodeQL and release GitHub workflows

Delete .github/workflows/codeql.yml and .github/workflows/release.yml. This removes the CodeQL analysis workflow (scheduled, push and PR triggers for main/master, JDK 17 + Gradle build) and the release-on-tag workflow (builds with Gradle and creates GitHub releases). These files were removed as part of CI/workflow cleanup or consolidation; update any CI expectations accordingly.
