[idd] scheduler: retain frames behind stalled owners

Browse Source 
Keep preparing the newest frame when both private owner lanes remain
referenced by a non-consuming timing client. Reuse only an unreferenced
completed buffer and continue serving eligible shared subscribers.

Track owner delivery separately from local retention so cadence advances
without acknowledging owner delivery or accepting phase feedback. Republish
the newest completed frame as soon as an owner lane becomes available.
