- PR #133877: fix(agent): match OpenRouter reworded guardrail 404 as provider_policy_blocked

A bug was identified where OpenRouter's reworded guardrail 404 responses no longer matched the existing pattern used to classify them as provider_policy_blocked, causing unwanted retries. The fix updates the pattern matching to recognize the new error wording.
