T1.5: Workflow with Array Iteration (with-items)

Tests that workflow actions spawn child executions for array items.

Test Flow:
1. Create workflow action with with-items on array parameter
2. Create rule to trigger workflow
3. Execute workflow with array: ["apple", "banana", "cherry"]
4. Verify parent execution created
5. Verify 3 child executions created (one per item)
6. Verify each child receives single item as input
7. Verify parent completes after all children succeed

Success Criteria:
- Parent execution status: 'running' while children execute
- Exactly 3 child executions created
- Each child execution has parent_execution_id set
- Each child receives single item: "apple", "banana", "cherry"
- Children can run in parallel
- Parent status becomes 'succeeded' after all children succeed
- Child execution count matches array length

Note: This test validates the workflow orchestration concept.
Full workflow support may be in progress.
