/**
 * OTLP Metrics Provider
 *
 * Central MeterProvider lifecycle module. Creates an OpenTelemetry
 * MeterProvider that pushes metrics via OTLP HTTP/JSON to the
 * configured collector (LGTM stack, Grafana Cloud, Mimir, etc.).
 *
 * Replaces the previous prom-client pull model (/metrics endpoint).
 * Data flow:
 *   OpenClaw diagnostic events → OTel instruments → OTLP exporter → Collector → Mimir → Grafana
