Iterates through the given ArchetypeChunk a whole contiguous run of available entities at a time, rather than one index at a time as ChunkEntityEnumerator.NextEntityIndex does. A run is a set of adjacent slots that are all available; batching lets a caller process a dense span in one operation. When every entity is available (the common case) this yields a single run [0, chunk.Count).
