Worker-projection thresholds (splat count, exclusive). nD projections run a
per-splat attenuation/compaction kernel and amortize the worker round trip
early; 3-D projections take the standard fast path and only pay off off-thread
once the copy itself is long enough to block frames (see processGSplatsData).
