Extend the LlmAgent single-turn guide with a section showing that `single_turn` composition is not limited to `LlmAgent`: a server-backed `ManagedAgent` can be a single-turn sub-agent via `mode='single_turn'`, is auto-exposed as an inline tool, preserves its internal events in the shared session, and is stateless per call.
