threejs-0007: Node.traverse() diamond recursion O(2^D); CLEAN for webpack/valhalla/traefik/wasmer/wasmtime; count 621->622
UNDF-2026-000000468: three.js src/nodes/core/Node.js:351 traverse() recurses
without a visited set; on shared-node (diamond) TSL shader graphs yields 2^D
callback invocations. D=10 gives 4093× overhead. Fix: add optional visited Set
parameter, default new Set() at root call.
Unit test: 10/10 PASS (ThreeJSNodeTraverseTest.java)
CLEAN markers written for: webpack (visitedModules WeakSet throughout),
valhalla (Dijkstra+BFS, no recursive DAG traversal), traefik (traverse() has
proper visited map), wasmer (petgraph+BTreeMap), wasmtime (SCC algorithms).
