Bump to 0.8.0

Control view button layout fixes (buttons sit next to each other, wrap
responsively on narrow screens), Replay view streamlined to match the
Control view (title includes the session name, buttons below the
header, matching "no devices connected" hint card, Play icon on
"Match & replay"), and the session-status Badge color mismatch between
the sessions overview and detail view fixed.
