GPU timing hook unavailable

Headless desktop export verification reports that GPU timing requires ara-render. This warning does not fail conformance verification; the report contains no measured GPU evidence.

#Common causes

• The conformance template has no renderer GPU-timing integration.

#Fixes

• Integrate renderer GPU measurements and publish them in ara_bridge::Telemetry.gpu_us through the bridge publisher; update verification to report the measured evidence.
