 * The `nitro.setup` hook runs during Nitro initialization (before the build), while
 * `printBuildReport` runs after the build, so sharing results is non-trivial. This is
 * a future optimization target.
 *
 * Unlike `printBuildReport`, this path does not receive `prerenderResult`, so routes
 * classified as `unknown` by static analysis (which `printBuildReport` might upgrade
 * to `static` via speculative prerender) are skipped here.
