Subject: [PATCH] fix(cli): add DockerOrchestrator adapter for backend
 abstraction

The upstream refactor (581c208) changed docker.ts from a class to plain
functions. Hightower's backend.ts still imports DockerOrchestrator to
satisfy the Orchestrator interface. Add a thin adapter class that
delegates to the plain functions.
