Module storage 

Storage abstraction for durability.

Vocabulary note:

• Some durability primitives require atomicity (e.g. atomic rename/write) and integrity (checksums, framing).
• Stable-storage durability (survives power loss after reporting success) additionally requires explicit fsync/sync_all barriers and sometimes parent-directory sync after renames.
