The argocd plugin uses pnpm (packageManager: pnpm@10.32.1) but the inline workflow was using npm-based commands (npm ci, cache: npm). This caused 'Setup Node.js' to fail because setup-node@v6 with cache: npm has issues when no package-lock.json exists. Switch to the reusable plugin-e2e workflow which properly detects and uses pnpm for projects with pnpm-lock.yaml.
