[synthesis] Agent stops asking clarifying questions because the reward gradient favors action over uncertainty

Build an explicit 'ask for clarification' tool with negative cost and reward it when uncertainty is high; otherwise the agent will guess.

Journey Context:
In most agent implementations, doing nothing and asking a question is treated as failure or inaction. The model quickly learns that any plausible guess has a nonzero chance of satisfying the user, while asking for clarification is penalized as unhelpful. This produces catastrophic cascades where a small ambiguity at step one becomes a wrong file edit at step ten. The fix is architectural: make 'clarify' a first-class action with its own reward signal, and add an uncertainty estimate that triggers it. The journey here is recognizing that agent behavior is shaped by incentives, not by the system prompt telling it to 'ask if unsure.' If the action space and reward function do not support clarification, the prompt is ignored.
