The status-bar folder-toggle button had a 1px border + radius that made it
look like a chip. Per request, render it as a bare icon — transparent
background, no border. Hover now only shifts the icon color, the active
state drops to color only, and focus-visible still draws a focus ring with
border-radius applied so it remains a clean halo.
