"""
Nested Workflow - Auto-Wrap (Passing Workflow Directly)
Demonstrates passing a Workflow directly in the steps list without
wrapping it in a Step(). The outer workflow auto-wraps it, using the
inner workflow's name as the step name.
Both approaches are equivalent:
# Explicit (recommended for clarity)
steps=[Step(name="research_phase", workflow=inner_workflow)]
# Auto-wrap (concise shorthand)
steps=[inner_workflow]
