Module worker_pool 

NUMA worker pool for memory allocation with first-touch policy.

This module provides dedicated worker threads that are pinned to specific NUMA nodes.

Architecture

• One worker thread per NUMA node (spawned lazily)
• Workers pin themselves on startup (immune to application thread management)
• Channel-based communication for allocation requests
• First-touch page allocation ensures correct NUMA placement
