Restyle the README: centered hero header, a screenshot row (timeline,
Places map, server/backup), and an emoji feature list. Refresh the feature
set and controls for what shipped since (smart search, the Places map +
cluster gallery, analog-stick map control) and link the releases page.
Screenshots live in docs/.
