Phase 1.2 migrated src/orchestrator_pm.py:86 to send_result(). The 3
tests in TestOrchestratorPM mocked src.ai_client.send, which would
break once Phase 1.2 was applied. (Confirmed: tests failed after
Phase 1.2 commit.)
Changes:
- Replace @patch(src.ai_client.send) with @patch(src.ai_client.send_result)
- Rename mock_send to mock_send_result throughout
- Wrap mock return_value with Result(data=json.dumps(...))
- Add "from src.result_types import Result" import
All 3 tests pass.
