Per RFC-WS-PRIMEVUE-PLAN-2-5 §8 step 1. Foundation scaffolding only —
no shell fixes, no Public Sans removal, no useShellUiStore changes
(P2–P6 scope).
Implements:
- theme darkModeSelector verified at '.dark' (already correct in
plugins/primevue/index.ts — config site is here, not theme.ts).
- src/config/navigation.ts: APP_NAVIGATION registry per AD-2.5-B1
(Dashboard entry only — v2-dashboard is the only v2 route today).
- src/composables/useBreadcrumb.ts: walkNavTree pure helper +
useNavBreadcrumb composable per AD-2.5-B1. The legacy meta-based
useBreadcrumb is preserved (consumed by AppTopbar, P1 may not
touch AppTopbar); P4 retires it and renames useNavBreadcrumb.
- src/components-v2/layout/AppBreadcrumb.vue: layout primitive
wrapping PrimeVue Breadcrumb, consuming useNavBreadcrumb.
- Tests: walkNavTree (4 specs, co-located), AppBreadcrumb mount
(2 specs, tests/component/layouts/).
Suite 564 → 570 (+6, all new specs green). vue-tsc clean. Scoped
ESLint clean.
