Successful run: https://github.com/github/copilot-engine-sdk/actions/runs/24145290995

Published package: https://www.npmjs.com/package/@github/copilot-engine-sdk

Changes

• Upgrade Node.js to 24 in the publish workflow to get an npm version recent enough to support OIDC token-based publishing to the npm registry
• Remove tee piping from npm publish command to avoid silent failures where tee masks non-zero exit codes
• Replace tee -a with >> for gh release create to preserve exit code propagation while still appending to the step summary
• Fix package.json repository URL — npm pkg fix corrected the URL to use the git+https:// prefix per npm conventions
