Add graceful workflow termination for RAI violations

- Add RAI_REFUSAL_PATTERNS list to detect jailbreak attempts, content safety
  violations, and out-of-scope requests
- Add _check_for_rai_refusal() function to scan conversation for refusal patterns
- Update workflow termination condition to exit when RAI refusal is detected
- Update TRIAGE_INSTRUCTIONS to explicitly not hand off after declining requests
- Update PLANNING_INSTRUCTIONS with content safety checks and explicit refusal
  behavior to prevent handoff to other agents after detecting harmful content

This ensures the workflow gracefully exits when any agent identifies a
jailbreak or content safety issue, rather than continuing to the next agent.
