MemoryAttachmentStorage
Class: MemoryAttachmentStorage
In-memory attachment storage implementation.
This is the default storage backend. It stores all attachments in a Map with O(1) access by ID. Suitable for development, testing, and small-scale deployments.
Limitations:
- Data is lost when the process restarts
- Memory usage scales linearly with stored data
- Not suitable for horizontal scaling (no shared state)
