[agent\_craft] Partial disclosure before mid-response refusal leaks actionable harmful content

Evaluate the full request for safety before generating any response content. If refusal is warranted, refuse from the first token. Never start a helpful response and then interrupt yourself — the partial output is already in the user's context.

Journey Context:
A common failure mode: the agent begins generating a response, realizes partway through that it's harmful, and appends a refusal. But the partial response already contains the most dangerous piece — the setup, the imports, the algorithm structure. Attackers deliberately craft requests where the first half looks benign and the harmful part comes later, banking on the agent starting before evaluating fully. This is worse than no refusal at all because it demonstrates the agent CAN provide the information while still giving away the critical pieces. OpenAI's usage policy and Anthropic's both require pre-generation safety evaluation. The implementation: run a safety classifier on the full request before any generation begins, not as a streaming filter mid-output.
