Previously Del always removed the most recently added section plane. Now a plane can be picked and deleted individually: - ViewportCore tracks a selected plane index, kept valid as planes are added (the new one becomes selected), removed, or cleared. - Clicking a gizmo with the section tool active selects that plane. - The section gizmo geometry is baked white and coloured via its per-plane tint, so the selected plane draws in a bright amber highlight while the rest stay red (unchanged look). - Del/Backspace removes the selected plane, falling back to the most recent one when nothing is selected.
