unplugin-auto-import scans src/composables/, so the new useRightDrawer
(Task 7) added a global + vue-module declaration. auto-imports.d.ts is
tracked (committed for editor/CI type resolution without a build), so
keep it in sync — same precedent as committing typed-router.d.ts. No
new symbol from useShellUiStore: src/stores is not in the auto-import
dirs (stores are imported explicitly), which is correct.
