/**
* txoko-metrics — Backend de métricas del nodo Bitcoin
* Txoko Node - System Metrics Server (v2 — ligero)
* Expone métricas del sistema via HTTP en localhost.
*
* Servidor HTTP Node.js que escucha en 127.0.0.1:4082.
* Sirve métricas del sistema y estado de Bitcoin Core al dashboard.
* Cambios v2 respecto a v1:
* - CPU medida leyendo /proc/stat dos veces con delta (sin spawnear `top`)
* - Por-núcleo con uso ACTUAL real (antes era el acumulado desde el arranque)
* - RPC de Bitcoin Core por HTTP nativo (sin `curl` → credenciales fuera de `ps`)
* - Peers contados con getnetworkinfo (sin getpeerinfo, que es enorme)
* - Caché con TTL: mide una vez cada pocos segundos, sirva a N navegadores
* - Todo asíncrono: nada bloquea el servidor
*
* CONFIGURACIÓN:
* Editar las variables de la sección "CONFIGURACIÓN LOCAL" con
* los datos de tu nodo antes de arrancar.
*
* ARRANCAR:
* Setup:
* npm install express
* node system-metrics.js
*
* O como servicio systemd:
* sudo systemctl start txoko-metrics
* Acceso: http://127.0.0.1:4082
