Progressive Lines loader for multi-additive-LOD datasets.
Wraps N LinesSpatialIndexLoader instances (one per additive_<i>
subgroup) using the Composite pattern. Mirrors
GSplatsProgressiveLoader / PointsProgressiveLoader.
Concatenation is the only line-specific wrinkle: segments indices
are LOCAL to each subgroup's vertex array, so we offset-adjust them
by the cumulative vertex count when concatenating.
