model: maintain speculative and confirmed state

Speculative state is computed eagerly by optimistically applying the expected events returned from mutations when they are executed. Confirmed state is computed from change events consumed from the backend via the model's input streams. Implements logic to rebase speculative updates on top of confirmed state as events arrive.
