[idd] capture: replay only completed frames

Browse Source 
Track the newest submitted and completed frame independently. Only
retain or replay a frame after its copy callback succeeds.

Keep the prior completed frame when a newer copy fails, and compare
publication sequences so out-of-order callbacks cannot move backward.
