docs(perf): dense-town FPS attribution (CPU-bound, GPU=0.5ms) + cellobject-batch spec
Attribution report: the handoff's "~12ms GPU" was a glFinish artifact; the clean
split measures GPU=0.5ms and a ~96% CPU-bound frame whose cost scales with visible
buildings. [CPU-PHASE] ranks it: cellobjects 3.5 / landscape 2.6 / partition 2 /
dynamics 1.2 ms; floods, punch-seal, clip-allocs, shells all <0.3ms (refuted).
Spec: iteration-1 fix = batch the per-cell WbDrawDispatcher.Draw calls in
DrawCellObjectLists into one cross-cell draw (the proven cells-shell pattern),
two-loop structure to keep particle-after-statics depth ordering. Target: dense
town solidly 144+.
