randrews 8263aff0c4 Add editor mode with archetype palette and click-to-paint
AppMode enum (Play/Edit) gates arrow-key input; a mode toggle in the
menu bar switches between them. Edit mode shows a SidePanel listing the
available archetypes (Empty, Wall, Object); clicking one selects it.
Clicking a board cell in Edit mode stamps it with the selected
archetype's default glyph. Mouse-to-cell conversion mirrors the
rendering origin math so clicks land on the correct cell.
