Pick the sidecar by the persona-facing protocol (input/chatbot.yaml
transport), not by every internal dependency of the product.

chatbot-api-sidecar_openbb is an API sidecar because the eval talks
/v1/messages; OpenBB itself is the MCP data layer behind the adapter, not a
chatbot-mcp-sidecar_* (those are for MCP surfaces the persona calls directly).
