Size the scope toggle to the pill row

ToggleGroup gained size variants on the SelectPill scale in spaceui
(cd42fd2 there); the search bar's scope control uses sm so the whole
refinement row sits on one h-7 baseline. Requires @spacedrive/
primitives 0.2.4; the workspace is bun-linked to the local package
until that publishes.
