Module pool 

Morsel-style query-level bounded worker pool for dynamic partition execution.

Workers are created once per query. Partition tasks are dynamically claimed from a shared atomic counter — a “morsel queue” — providing natural load balancing: faster workers automatically process more partitions.

This is the only parallel execution mechanism (replaces the per-Gather ParallelPartitionCoordinator). The TaskScheduler trait abstracts over pool implementations.
