sema: clamp the pin-rewind at ring start - never wrap below zero
The rewind used entries - (N - get) for get < N, which for an empty ring
(get=0, put=0) jumped last_get to entries-8, so the pump read ring slots the
producer had never reached and could execute stale/garbage entries. Replay
only recently consumed slots, clamped at 0.
