public interface PQEntry
Interface for priority queue entries with sequence tracking.

Defines the contract for elements stored in priority-based blocking queues. Provides methods for accessing priority levels and sequence numbers to ensure proper FIFO ordering within same priority levels.

Used by PriBlockingQueue and CoDelPriorityBlockingQueue to maintain insertion order while supporting priority-based selection and removal operations.
