list_trees

List the model's navigation trees. Trees live in their own collection (not returned by search_nodes), so this is how you discover a tree's ID before calling update_tree or delete_tree. Returns id, name, description, folder_id, tags, and branch_count (number of top-level branches). Filter by name or folder.
