get_next_task
Given a 'requestId', return the next pending task (not done yet). If all tasks are completed, it will indicate that no more tasks are left and that you must wait for the request completion approval.
A progress table showing the current status of all tasks will be displayed with each response.
If the same task is returned again or if no new task is provided after a task was marked as done but not yet approved, you MUST NOT proceed. In such a scenario, you must prompt the user for approval via 'approve_task_completion' before calling 'get_next_task' again. Do not skip the user's approval step.
In other words:
- After calling 'mark_task_done', do not call 'get_next_task' again until 'approve_task_completion' is called by the user.
- If 'get_next_task' returns 'all_tasks_done', it means all tasks have been completed. At this point, you must not start a new request or do anything else until the user decides to 'approve_request_completion' or possibly add more tasks via 'request_planning'.
