tracing.New silently no-ops when OTEL_EXPORTER_OTLP_ENDPOINT is unset, so a misconfigured or black-holed endpoint is invisible until you notice the absence of spans. Log the active endpoint when tracing is enabled, and log the reason when it is disabled.

tracing.Newsilently no-ops whenOTEL_EXPORTER_OTLP_ENDPOINTis unset, so a misconfigured or black-holed OTLP endpoint is invisible until you notice the absence of spans in APM. This logs the active endpoint when tracing is enabled, and the reason (enabled flag + endpoint) when it is disabled, so the export state is obvious from cachew's own startup logs.
