URL: https://github.com/apache/skywalking/pull/13930
### Summary
Add OAP-side support for Node.js runtime metrics reported by
`MeterReportService` from skywalking-nodejs (merged in
apache/skywalking-nodejs#139, commit `36df516`).
### Changes
- Add `nodejs-runtime.yaml` MAL analyzer with 6 rules →
`meter_instance_nodejs_*`:
`process_cpu`, `heap_used`, `heap_total`, `heap_limit`, `rss`,
`external_memory`
- Register analyzer in `application.yml`; add unit test data
(`nodejs-runtime.data.yaml`)
- Add E2E MQE assertions for all 6 meters
(`test/e2e-v2/cases/nodejs/e2e.yaml`)
- Add setup doc (`dashboards-nodejs-runtime.md`), menu entry, and
`changes.md`
### Related PRs
- Agent: apache/skywalking-nodejs#139 (merged)
- UI: skywalking-horizon-ui (General layer instance dashboard widgets)
### CI
Node.js E2E and meter-related jobs pass on fork. Unrelated flaky failures
(Go agent image, Alarm/Istio E2E) do not affect this change.
### Test plan
- [ ] OAP unit test: `nodejs-runtime.data.yaml` MAL rules
- [ ] E2E: `Agent NodeJS Backend` / `Frontend` jobs assert 6
`meter_instance_nodejs_*` metrics
- [ ] With UI PR: General → Instances → Node.js instance shows 6 runtime
widgets
