The skill-map response gave units -> nodes with id/title/status but no way to map a node to its lessons, and no other endpoint fills that gap (/api/progress/nodes doesn't either). Any client rendering the map needs this to know which lesson to open when a node is tapped. The ids are already computed in the cached _grade_tree; this just surfaces them. Additive and backward-compatible; content tests pass. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
