The distributed router wraps backend clients in InFlightTrackingClient so
the eviction logic knows which replicas are actively serving. Every
inference method must be wrapped: track() increments in-flight on entry
and decrements (plus fires onFirstComplete, which releases the load-time
reservation) on return.
SoundDetection was added after the tracking client and never got a
wrapper, so its calls fell through to the embedded passthrough Backend.
The increment/decrement never ran and, critically, onFirstComplete never
fired, so the reservation set at model load was never released - leaving
in-flight stuck at 1 and the replica permanently ineligible for eviction.
Wrap SoundDetection like the other non-LLM methods and cover it in the
"non-LLM inference methods track in-flight" table test.
