Module EmitOTLPSpan 

Fire-and-forget OTLP span exporter. Lifted from Mountain’s IPC/DevLog/EmitOTLPSpan so Air / Echo / Rest / Grove / Mist / SideCar all share the same raw HTTP path. Single failed POST flips OTLP_AVAILABLE to false so a missing collector doesn’t tax every emit. Release builds compile out via cfg!(debug_assertions).
