What
When a turn falls back after a model refusal, the agent's displayed model is rewritten to the model actually used, and the fallback message now carries a scope.
Details
A new agent event kind propagates turn effort together with the turn model.
The async-agent reader applies system/model_refusal_fallback by rewriting the agent's model rather than leaving the old one on screen.
The optional scope field was added at three emit sites and in the parser.
