/**
 * Metrics Collector Service
 *
 * Subscribes to OpenClaw diagnostic events and converts them to OpenTelemetry
 * signals pushed via OTLP to the configured collector (LGTM stack, Grafana Cloud, etc.).
 *
 * Three pillars, one handler:
 *   - Metrics: operational gauges (sessions, cost, context, queues) → Mimir → Grafana dashboards
 *   - Logs: verbose structured log records for ALL events → Loki → Grafana Explore
 *   - Traces: agent lifecycle spans (model calls, messages, webhooks) → Tempo → Grafana Explore
 *
 * Log-to-trace correlation: span-producing events include trace_id in the log record,
 * enabling Grafana's "Logs to Traces" feature (click Loki log → jump to Tempo trace).
