[launcher].modes now lists calc/cmd/url alongside apps, sections is
enabled, and two new keys (search_width/search_radius) let an embedded
launcher theme declare its search-state capsule geometry, defaulting to
the idle value when a theme omits them. Also gives spotlight's [bar.slots]
a widget:left_of_stats entry so a Lua widget requesting that placement
(e.g. git-branch-widget.lua) has a home instead of being silently dropped.
