Generate 1x2/2x1 dominoes, 2x2 (square + 4 L-trominoes) and all
connected 3x2/2x3 polyominoes as R/G/B channel masks, reusing the
distance-based concentric-ring format that reproduces box_r/g/b
exactly. Outer silhouette keeps a 1px margin; connected cells stay
seamless. Each shape ships a {class="moveable"} .meta so getAllAssets
auto-registers it as a GenericMoveable.
Wire the occupied-cell shape (precomputed once by getAllAssets via
getCellsFromSprite) through to entities: createEntity now passes the
cached cells as cellShape, so an L/U/notched block collides on its real
cells and its gaps read as empty space. Fix the per-colour cache that
was reset every channel so only one colour survived.
