     * At build time, for each dynamic segment, we compute the list of static
     * sibling segments that exist at the same URL path level. This is used by
     * the client router to determine if a prefetch can be reused.
     *
     * For example, given the following file structure:
     *   /app/(group1)/products/sale/page.tsx -> /products/sale
     *   /app/(group2)/products/[id]/page.tsx -> /products/[id]

     *
     * This accounts for route groups, which may place sibling routes in
     * different parts of the file system tree but at the same URL level.
     *
     * A value of `null` means the static siblings are unknown (e.g., in webpack
     * dev mode where routes are compiled on-demand).
