Function createInMemoryAdapter

createInMemoryAdapter(): StorageAdapter
Create a volatile, in-process StorageAdapter backed by a plain Map. All data is lost when the process exits.

Intended for testing and development only. Because there is no persistence layer, linkToUser is a no-op and deleteOldSnapshots prunes in-memory history without tracking a deleted-row count.

Returns StorageAdapter
A fully initialised (eager) StorageAdapter instance.
Example
```
const adapter = createInMemoryAdapter();
await adapter.init(); // no-op but keeps the API consistent
```
