"""
Test 9: DeepAgent test with enable_planning, enable_filesystem, subagents, filesystem_backend

Success criteria:
- DeepAgent properly creates todos and executes them all properly
- Files exist that we want to create as described in the Task description
- DeepAgent registers and calls subagents properly
- We use CompositeBackend properly
- We check attributes and logs for that
