Row exit now clears the preview only when the highlight still points at
that row. Moving between rows can fire on_enter before the previous
row's on_exit, so the unconditional clear wiped a freshly highlighted
row (notably when returning to the first row). Guarding the clear fixes
the highlight not reappearing.

Add a scene hover_highlight handle that renders an entity with the
selection colour without joining the real selection. The cycling list
box sets it on row enter / clears on exit, so hovering a row glows the
matching object in the drawing.

Replace the repeat-click cycling with a list box: when a click lands on
two or more overlapping objects (cycling on), a small list of the
candidates opens at the cursor. Picking a row adds that object to the
current selection (accumulate); clicking outside dismisses it. A single
object under the cursor falls through to the normal click.
