Returns the complete hierarchical structure of a course including its lesson groupings and lessons in a scope and sequence format.

The structure follows this hierarchy:

• Course → Lesson Groupings (can be nested) → Lessons

Note: Different curricula use different organizational structures. Lesson groupings might be called units, modules, chapters, sections, themes, etc. depending on the curriculum. The groupName property in each lesson grouping indicates what type it is (e.g., "unit", "section", "module").

Use this endpoint when you need to:

• Display the complete course outline or table of contents
• Navigate the course structure programmatically
• Build a course curriculum map or scope and sequence view
• Understand the full instructional progression of a course

The view parameter controls the level of detail:

• summary: Returns only essential navigation fields (identifiers, names, positions)
• full: Returns complete objects with all properties for each element
