"""Throwaway smoke: drive the real agent harness against the live llama.cpp server.

Loads a fixture session and runs one SPEAK turn and one ACT turn through
``run_agent_turn_streaming``, printing streamed tokens, tool activity, and the
final TurnResult. Proves the full agent-forward pipeline end-to-end.
