bread-theme's shared .title rule (1.4em bold) was a bare class selector
that also matched libadwaita's internal row/window-title labels, which
carry the same "title" class. That's what inflated breadman's settings
row titles to ~24px. Scoping the name to .page-title here (the only
consumer of the old class) and bumping bread-theme to the dev branch
where the rename lives.
Replaces the old in-window onboarding wizard with a real screen-wide
tour: dim + spotlight cutout around the actual on-screen component
(breadbar, breadbox), floating callout teaching the shortcut, and
event-driven confirmation via real Hyprland/breadd signals instead of
click-through fakery.
