perf: optimize multipleSplats perfomance

Reduces buffer swaps from O(2N) to O(2), N = number of splats Minimizes expensive WebGL context state changes Processes all velocity updates first to keep similar operations contiguous then handles all dye updates for better texture cache utilization
refactor: restructure
