Reverse-map a graph node id back to its (key, id?, workspace) representation, the inverse of
resolveUrl. A linked node (a <prefix><variant> segment) maps to the grammar's linked key with the
variant as its id. Any other node maps through the most specific binding whose shape addresses its id,
so the answer is the same whether or not the node is loaded; an id no binding addresses returns
Option.none().
