profile: per-LOD whole-view breakdown for the four-strate owner world (L73, no world change)

Browse Source 
FI/TN/VS (legacy compiled-analytic) skip ZERO tiles at every LOD and evaluate ~44k density
points per LOD0/1 tile; SW skips 359/512 at LOD0. The whole-tile skip requires a native
tile with a uniform verdict, and the legacy paths return Mixed/unknown (R39 notes attached).
Opt-in stage timers, sampled field timer, per-LOD classification and composer counters.
