Handle an empty restack plan before starting Bubble Tea.

createState always returns &state, even when PlanForRestack returns zero operations. Therefore, this nil check does not run for a no-work restack. The command still calls RunBubbleTea and can emit terminal control sequences.

Return a nil state or a no-work sentinel when the plan is empty.

In `@cmd/av/restack.go` around lines 60 - 63, Update createState to return nil or
the established no-work sentinel when PlanForRestack produces zero operations,
so the existing state == nil guard prevents RunBubbleTea from starting for an
empty restack plan.

vm.state = state
return uiutils.RunBubbleTea(vm)
