Counts total transfers in current namespace.

Direct ETS access - does not go through GenServer.

@spec delete(String.t()) :: :ok

Deletes a transfer from the store.

@spec find_by_destination(String.t()) :: [map()]

Finds transfers by destination account in the current request scope.

@spec get(String.t()) :: {:ok, map()} | {:error, :not_found}
