Detailed Description

Bounded deferred reclamation for a writer-owned lifetime domain.

A full queue applies synchronous backpressure. Call drain() before releasing callback code or its owner (in particular before module unload); destruction also drains. Callbacks reclaim storage in task context and must not invoke queue operations. Do not enqueue while holding locks needed by a callback.
