Refused evaluations can now produce a distinct 'policy_refusal' block reason instead of a generic unavailable one

What

When Claude Code cannot get an evaluation result because it was refused, it now can produce a specific blocking result with failure mode policy_refusal and reason category policy_refusal, rather than falling through to the generic 'unavailable' handling.

Why

This gives refusal-caused blocks a distinct, identifiable reason instead of lumping them in with other unavailable-result cases, which should make it clearer when a refusal specifically was the cause.
