 * Creates a FIFO queue with O(1) membership check and O(1) cancellation.

 * @remarks
 * Backed by an array (for ordering) and a Set (for fast lookup/cancel).
 * Cancelled entries are tombstoned (set to null) and skipped on dequeue.
 * The array is compacted when the head pointer exceeds half the array length
 * and is at least 64 entries deep, amortising the compaction cost.
