Throwaway, branch-only routes under app/instant-nav-demo/ (hub + fast/slow/[item]) to exercise 16.3 shell prefetching + partial streaming on the preview deploy. Also enables experimental turbopackFileSystemCacheForBuild and turbopackRustReactCompiler. Verified: build + typecheck + lint green on 16.3.0-preview.5.

This PR exists to spin up a deploy preview so we can feel out Next.js 16.3's
Instant Navigations on a real deployment. It rides the
@previewnpm tag, whichis pre-production ("changes are likely before stable"), so it stays a draft until
16.3 ships stable.
What this does
Bumps the starter to Next.js 16.3.0-preview.5 and turns on the instant-navigation
config so the preview deploy exercises shell-based prefetching.
next+@next/bundle-analyzer→16.3.0-preview.5(exact-pinned). React unchanged.partialPrefetching: trueadded (the 16.3 successor to the experimentalprefetchInliningstepping stone, which is removed).cacheComponentswasalready on;
experimental.cachedNavigationsstays — still a valid flag in 16.3.app/loading.tsxhardened from a placeholder word into an accessible skeletonshell, so navigations land on a real shell instead of "Cooking…".
