Adversarial evaluation for Agent Assist: ship agents that survive production

Introduced automated, multi-turn adversarial evaluation (red-teaming) for DataRobot Agent Assist. This feature subjects agents to prompt injection, scope escalation, unexpected behavior, and persistence attacks. It includes breach detection, automated generation of remediation patches, developer approval workflows, and retesting. Production systems are isolated, with configurable read-only tool opt-ins. Evaluation reports provide pass/fail metrics, breach details, and fix audit trails.
