chore: refresh Node 24 maintenance pass

[dex-the-ai]

Summary

• update the Node.js test workflow from Node 20 to Node 24
• refresh the supportable patch-level Babel/Jest packages and regenerate package-lock.json
• add QueryScanConsistency.RequestPlus to the airline/airport list handlers so the integration suite reliably sees newly inserted fixture documents on the current runtime/SDK stack

Verification

• npm install
• npm test ✅ (19/19 suites passed)
• npm start ✅
• curl -I http://127.0.0.1:3000/ ✅
• curl http://127.0.0.1:3000/api/v1/airline/airline_10 ✅

Evidence

• Baseline verification on this sweep still had two red suites (api-airport-list, api-airline-list) after the env/bootstrap step; both were resolved by restoring request-plus consistency on the list queries.
• Final passing logs are in tutorial-maintenance/runs/nodejs-quickstart/2026-06-09T0319Z/post-update-tests.txt.
• Live walkthrough artifacts are in tutorial-maintenance/runs/nodejs-quickstart/2026-06-09T0319Z/walkthrough.txt, tutorial-maintenance/runs/nodejs-quickstart/2026-06-09T0319Z/screenshots/swagger-ui-home.png, and tutorial-maintenance/runs/nodejs-quickstart/2026-06-09T0319Z/videos/swagger-ui-walkthrough.webm.
• npm audit is improved but not yet clean; the remaining 7 vulnerabilities are in the Express 4 / qs chain and the available fix path is larger than this maintenance pass.

Notes

• I kept this PR to Node 24 CI alignment plus patch/minor dependency work; larger framework upgrades like Express 5 are still out of scope.

Media evidence

• Auto-attached reviewer-facing media from the local verification artifacts captured during this run.
• This keeps the main PR body self-contained instead of relying on a follow-up comment for visual proof.

Code Review

This pull request updates several dependencies in package.json and configures QueryScanConsistency.RequestPlus for Couchbase queries in both airlineController.js and airportController.js. The reviewer recommends making the scan consistency configurable via an environment variable rather than hardcoding it to RequestPlus, as doing so can cause performance bottlenecks and high latency in production environments.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

@dex-the-ai do we need to add the scanConsistency to accommodate the dependency upgrades? Also, the test is failing.

Follow-up after rechecking this more carefully locally:

• I pushed 3efd602 to restore QueryScanConsistency.RequestPlus on the two list endpoints.
• After clearing stale local airport_test_* docs from my travel-sample bucket and rerunning the targeted list tests, both api-airline-list and api-airport-list failed immediately without the consistency override and passed again with it restored.
• I then reran the full suite with npm run testGA; all 19 tests passed.
• Because of that revert, the couchbase import in airportController is needed again.

So the current PR state keeps the Slack notifier v2 upgrade from f543460, but it also brings the list-query consistency change back because the local quickstart/test flow is still flaky without it.

GitHub checks are rerunning on this push now.
