- Sidebar "Apps" section renamed to "Build"
- Each app now links to /build?app=<name>&root=<path> so the browser
opens scoped to that app's subdirectory only
- Build page shows an empty-state prompt when no app is selected
- File tree header shows the selected app name, breadcrumb shows
relative path within the app (strips the root prefix)
- Wraps useSearchParams in Suspense for Next.js static rendering
