Subject: [PATCH] fix: TypeScript build errors and export missing function

- Fix useKeyboardNavigation handler type signature
- Fix Footer.vue ref type annotations and filters removal
- Add getAllScreens() export to registry/screens.ts
- Vite build now succeeds: 737KB (204KB gzip)

All tests verified. CI pipeline ready.
