- New: next-character predictions in EZ mode. After picking a
  candidate, the bar surfaces likely follow-up characters mined
  from the bundled phrase corpus (e.g. 信 → 件 / 箱 / 封 / 賴 /
  任). Predictions are tap-only, with no 1–0 shortcut labels so
  EZ digit roots keep their normal keystroke meaning; any new
  keystroke dismisses the strip.
- Build: bump Android Gradle Plugin to 9.2.1 and the Gradle
  wrapper to 9.4.1.
- Polish: refresh the app launcher icon and drop a few orphaned
  foreground bitmaps.
