"""
Tests for CLI task monitoring commands.

Tests the task monitoring CLI commands that use the actual task_state API:
- BackgroundTask.create + add_task (not create_task)
- update_task (not update_task_status)
- get_background_tasks (returns list, not dict)
- task.id (not task.task_id)
- task.start_time (not task.created_at)
