Class: SpriteSizeSystem

Mirrors a Raw-mode sprite's natural size into its host UITransform — in PreRender, straight from the loaded asset, so the size is known BEFORE WidgetSystem / LayoutSystem / ScrollViewSystem consume it that same frame. SpriteRenderSystem does the same adoption, but only in the Render phase (after those systems) and only once the backend resource exists — a frame too late for layout, which is why a Raw sprite inside a Layout would pack at the default 100×100 until it caught up.

Behaviour matches SpriteRenderSystem's Raw adoption exactly, just earlier:

• adopt once per (entity, asset); re-adopt when the asset changes;
• skip the aspect-lock "missing dimension" case (exactly one of width/height left ≤ 0), which SpriteRenderSystem fills from the texture aspect and flips to Custom;
• no-op for Custom sprites and until the asset has loaded.
