fix(receiver): harden prefetch and listener lifecycle (#645)

* fix(receiver): harden prefetch and listener lifecycle

Track delivery and prefetch capacity ownership across shutdown paths.
Close pending listener reads, preserve late deliveries, and restore
fail-fast transport error propagation.

Keep middleware accounting balanced, report discarded deliveries, and
retain deferred lifecycle diagnostics when task group failures overlap.

* fix(receiver): tighten prefetch ownership checks

Reject invalid prefetch values before receiver retries and retain delivery accounting until execution capacity is acquired.

Add deterministic coverage for CLI defaults, cancellation races, and listener lifecycle cleanup.

Refs #528
