create_tree

Create a navigation tree (ModelTree): a named, ordered tree structure over the graph, used as a reading-oriented browse structure (Reader Workspace, publishing site nav, report chapter order). A tree is an ordered list of branches; each branch may have a label, description, a seed (a filter expression selecting its node(s) — e.g. {"OfType":{"type_id":""}}, {"HasId":{"ids":[""]}}, {"FilterRef":{"filter_id":""}}), an expansion (follow a relationship from the seed), an ordering, and nested children. Use list_trees to discover existing trees. Applied immediately.
