An embarrassing bug...
The insert function in tree.go was incrementing t.size unconditionally after a successful write, so every Update call inflated Len() even though no new route was added (the methods map increment was correctly gated on modeInsert, but t.size++ was not). This fix moves t.size++ inside the modeInsert guard so Update no longer drifts the route count.
