/**
 * OTLP Traces Provider
 *
 * Central TracerProvider lifecycle module. Creates an OpenTelemetry
 * BasicTracerProvider that pushes trace spans via OTLP HTTP/JSON
 * to the configured collector (LGTM stack, Grafana Cloud, etc.).
 *
 * Mirrors the otel-metrics.ts pattern exactly:
 *   - Local provider only (NO global registration — avoids conflict with diagnostics-otel)
 *   - Fire-and-forget emission via BatchSpanProcessor
 *   - Same shared resource identity (service.name=openclaw, service.namespace=grafana-lens)
 *
 * Data flow:
 *   Diagnostic events / tool calls → OTel Span → OTLP exporter → Collector → Tempo → Grafana
