The phase 2 code review surfaced four follow-ups left after merge.
The joint accessor indexed body.valid without checking its length,
so a short valid array could crash on out-of-range access; it now
guards i < body.valid.count. The viz mode name list was rebuilt on
every modeName() call, so it is hoisted to a static constant. A
Metal shader compile test is added to catch scene.metal regressions
in CI. The dead SceneView placeholder, superseded by LayeredSceneView,
is removed.
