"""SmolmachinesBottle — runtime handle stub (PRD 0023 chunk 1).

The chunk-1 backend doesn't launch VMs yet, so this class only
exists to make `SmolmachinesBottleBackend.launch` resolvable at
import time. Every method raises NotImplementedError; chunk 2
gives it real `smolvm machine exec` plumbing."""
