feat(08.1-02): update MockAgentManager to schema-aligned scenarios

- Change MockAgentScenario from outcome-based to status-based discriminated union
- Align with agent output schema: done/question/unrecoverable_error
- Update completeAgent() to handle new status types
- Update resume() to use new scenario format
