test(highway_3d): cut-16 scene-init — setter-call kill tests + execution smoke + pinned DI count

§10 kill tests added (10 source-scan assertions): - initScene body calls setRen(, setScene(, setPNote(, setWrap( - buildBoard body calls setBoardStringStartX(, setFretWireMats( - _bgLoadSettings body calls setActivePalette(, setCameraMode(, setGlowMul( - _bcSyncMode body calls setBcCtrl( Each kills silently when its setter call is gutted — catches omission not covered by the class-killer (which only catches assignment to DI param names). §11 gate-2 execution smoke: new-Function harness with Proxy-based recording DI stubs. With null canvas, initScene() returns false immediately (early guard path). Documents WebGL gap: T.WebGLRenderer requires a real canvas; source-scan kill tests cover the allocation paths. Sloppy-mode write gap documented; ESLint no-undef compensates. Anti-vacuity test updated: floor ≥150 kept; exact pinned count 183 added (line-first-identifier extractor; comma-split total ~397 because many lines pack pairs like 'getX, setX,' — both are counted in the comma-split).
