Device App-info screenshot showed the launcher only renders the central ~54%
of the adaptive icon, clipping the ring. Calibrated the ring to scale 0.50 so it
lands at the visible circle edge; grid to 0.55. Bump versionCode 8 so launcher3
refreshes its icon cache (it keys the cached bitmap by versionCode).
