style: redesign social share widget with terminal-native aesthetic

Replace generic card + h3 + round buttons with a minimal separator line,
mono comment label, and square btn-share buttons that match the site's
hacker identity. Icons scaled to 22px inside 50x50px touch targets.
Hover/focus states use the site's accent glow pattern.
