Subject: [PATCH 1/2] Add Qlty code coverage reporting to CI

node 24 matrix entry in the test-node-versions CI job.

Subject: [PATCH 2/2] Fix: install @vitest/coverage-v8 at runtime in CI

Instead of adding to package.json (which breaks the lockfile), install
the coverage dependency on-the-fly during the coverage generation step.
