++Telemetry (openvibe-sdk 0.46, `platform.telemetry-sample@1`): requests are aggregated by route template, method and status class,
++never raw URL; `/shared`, static assets, health, readiness and `/metrics` are skipped. `server/app.js` builds `createHttpTelemetry`
++and mounts its middleware; `server/index.js` writes one `http.request` sample per key plus the active-requests, p95 and event-loop-lag
++gauges to `telemetry_samples` every minute and on stop, and deletes rows older than 14 days daily (`migrations/0004_telemetry.sql`).
