otel_talker

OpenTelemetry log bridge for package:talker.

Mirrors every Talker log / error / exception into the OpenTelemetry logs pipeline so structured records flow to your OTel backend while Talker keeps rendering its dev-friendly output. Records inherit trace_id / span_id from Context.current, so log calls inside a Tracer.startActiveSpan block are auto-correlated with the surrounding span.
