* Workflows API Validation Test Suite
* Story 2.1: Validate & Test Workflows API
*
* Comprehensive validation and testing of all 8 implemented Workflows API methods
* against live n8n instance and documentation.
*
* Test Coverage:
* - GET /workflows (list_workflows) - 7 tests
* - GET /workflows/{id} (get_workflow) - 5 tests
* - POST /workflows (create_workflow) - 6 tests
* - PUT /workflows/{id} (update_workflow) - 6 tests
* - DELETE /workflows/{id} (delete_workflow) - 5 tests
* - PUT /workflows/{id}/activate (activate_workflow) - 6 tests
* - PUT /workflows/{id}/deactivate (deactivate_workflow) - 5 tests
* - Workflow execution (execute_workflow) - 5 tests
* - Multi-instance validation - 3 tests
* - Error handling validation - 6 tests
*
* Total: 54+ comprehensive validation tests
