Release v16

Add swipe-to-dismiss gesture on article cards

Swiping left or right reveals a soft peach dismiss background with
an archive icon. Past 110px threshold the card flies off and the
article is removed from storage without being marked as read.
Uses Gesture Handler Pan + Reanimated for smooth animation.
