"""The orchestrator routes only dedicated-backend providers through the registry.

GROK gets the GrokCliProvider; Anthropic / Ollama Cloud / self-hosted (and any
unknown value) return None so ``_spawn_container`` runs its built-in Claude Code
path unchanged. This keeps the GROK addition purely additive.
