New Flutter app (~/habit_stack) gets an on-style launcher icon from the
shared family: two interlocking stadium-ring outlines, sized so the
72px stroke leaves a genuinely hollow interior at launcher size. Accent
matches the app's own ThemeData seedColor (#66BB6A), not already
claimed by a sibling app.
Also whitelists com.kuhy.habit_stack in phone_focus_mode/config.sh (both
the always-on productive-apps list and the night/curfew health-tool
list) and redeploys, since an unwhitelisted com.kuhy.* app is killed
within ~1s and would otherwise look like an install failure.
