What's New
Hierarchical Queues
Adds hierarchical queue capacities so parent queues can limit parallelism across child queues while still preserving FIFO behavior within each child queue. This release includes the queue accounting, transaction, and cleanup changes needed to support scoped capacities reliably.
Reliability Improvements
Includes follow-on fixes around queue acquisition, scoped cleanup, process detection, signal handling, and test stability so the new queue behavior is solid in practice.
