Crate dynamo_memory 

Clean, minimal storage API for v2 block manager.

This module provides a simplified storage abstraction with:

• Single trait for type erasure (MemoryDescriptor)
• Concrete storage types (no trait implementations required)
• Composition-based NIXL registration via NixlRegistered<T> wrapper
• RAII with proper drop ordering (registration handle drops before memory)
