Defined in:

Overview

Uninstalls one or more components. It deletes only files unique to the removed items — never the shared base (ui_component/ui_helper/shadwire.css) and never a file still listed by another installed entry — then prunes any emptied directory under the components root and drops the items from shadwire.json. Importmap pins that no remaining component uses are reported (not auto-removed — dep cleanup is left to the user). Confirms first unless --yes.
