Pure helper splitting a frame's entities into live-dynamic / per-cell statics / outdoor scenery, by the same precedence as WbDrawDispatcher.ResolveEntitySlot (serverGuid first — live entities have no ParentCellId). Feeds the per-cell DrawInside loop. 3 unit tests, GL-free. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
