Criterion benches over InferenceEngine::infer for cog-person-count and
cog-pose-estimation, on Device::Cpu with the real shipped safetensors
weights (asserts candle backend so the stub is never silently benched),
over a fixed CSI window after a warm-up forward.
HOST-MEASURED steady-state medians (idle box): ~305us each. This is the
recurring per-frame cost and is explicitly NOT the pose manifest's
cold_start_ms_avg=5.4 (a different measurement, weight-load included, taken
on ruvultra/RTX 5080) -- the two are labelled and not conflated.
Closes the ADR-159/160 deferred cog inference-latency item. No production-
code behavior change.
