Removes the parent-child relationship between a task and its subtask by setting the subtask parentTaskId to null. The subtask itself is not deleted - it becomes a standalone task again. This is useful when reorganizing task hierarchies or when a subtask needs to be promoted to a main task. The parent task identifier can be either a UUID or a numeric shortNumber. The subtaskId must be a valid UUID. Requires Tasks.editAnyTitleAndDescription permission.
