Based on: - https://github.com/vercel/next.js/pull/88834 - https://github.com/vercel/next.js/pull/88989 - https://github.com/vercel/next.js/pull/88998 --- Adds optimistic routing, enabling the client to predict route structure for URLs that haven't been prefetched yet. When navigating to a URL like /blog/post-2, if we've previously learned the pattern from /blog/post-1, we can predict the route structure without waiting for a server response. The client learns route patterns from server responses and builds a trie indexed by URL parts. When a cache miss occurs, we check if the URL matches a known pattern. If so, we create a synthetic cache entry from the template, allowing immediate rendering of loading boundaries. Static siblings (like /blog/featured alongside /blog/[slug]) are tracked to avoid incorrect predictions — we only predict dynamic routes when we're confident no static sibling matches.
