- MessagesScreen: shrink message boxes to fit content and anchor them
right (outgoing) / left (incoming), like typical messengers; move
the [+ send] compose button to the right edge to match; fix its
frame margins (no descenders in the label made the symmetric padding
look uneven) and reclaim the freed 2px for the message list.
- KeyboardWidget: add Hold-Enter cursor-positioning mode (LEFT/RIGHT
move, UP/DOWN jump to start/end, Enter/Cancel exit) with a visual
"CURSOR MODE" indicator, so edits and inserts can target any point
in the typed text instead of always the end.
