Bump GitHub Actions runtime to Node 24

GitHub will stop supporting the Node 20 runtime for GitHub Actions on
June 2nd, 2026 (see https://github.blog/changelog/2025-12-05-github-actions-update-on-node20-deprecation/),
so the `runs.using` field in action.yml is switched from `node20`
to `node24`.

Both CI workflows gain an explicit `actions/setup-node@v6` step
pinned to `node-version: 24` so that `npm ci`, the build, and the
test suite all run under the same Node version that the action will
use at runtime. Without this step, CI would use whatever Node version
the runner image happens to ship, which may not yet be v24.
