/**
 * Task Pool State
 *
 * Shared state for task pool pause/resume functionality.
 * This is kept separate to avoid circular dependencies between
 * task-service.ts and routes/tasks.ts.
 *
 * State is in-memory and resets on server restart.
 * By default, the pool is PAUSED (closed) - admin must explicitly start it.
 * This prevents workers from immediately grabbing tasks on deploy before
 * the system is ready.
