Add a hidden-entity set to the scene that the tessellation visibility test skips, so hidden objects neither render nor hit-test. New commands ISOLATEOBJECTS (show only the selection), HIDEOBJECTS (hide the selection) and UNISOLATEOBJECTS (restore). An ISO status pill lights up while anything is hidden and restores everything on click. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
