Expand description
Multi-consumer extension: bounded MPMC ring with tail-sequence CAS.
Disruptor-style barrier: per-slot sequence numbers gate both
producer claim (CAS the tail) and consumer claim (CAS the head).
Multiple consumers race; the loser sees a stale head and retries
with the new value. Optional MpmcQueue::cas_retries counts
contention for callers wiring it through the metrics feature.
Both MpmcQueue::try_enqueue and MpmcQueue::try_dequeue are wait-free in the
uncontended case and bounded-retry under contention.
