Module storage 

Storage layer for d-engine.

This module provides pluggable and extensible storage components for persisting Raft state and application data. It defines core traits, adapters, and utilities to support different backend implementations.

Key responsibilities include:

• Managing Raft log entries and snapshots.
• Providing an abstraction layer (StorageEngine) for persistence.
• Supporting in-memory buffering and disk-backed storage (e.g., via Sled).
• Coordinating state machine application and snapshot lifecycle.

This module is designed so developers can easily implement custom storage backends without changing the Raft protocol logic.
