Simplify splats to a target count using NanoGS progressive pairwise merging.
Instead of discarding low-visibility splats, this iteratively merges nearby
similar splats into single approximating Gaussians using Mass-Preserving
Moment Matching (MPMM), preserving scene structure and appearance.
Removal is allocated at a uniform rate everywhere; for the adaptive variant
call decimateSourceAdaptive() directly.
