Uncapped chat history retention, dev overlay route overrides fixed

Vercel's chat library now supports unlimited per-user history retention, and Next.js fixes stale route info in the dev overlay.

The vercel/chat history feature now accepts `history.user.maxPerUser: false` and the legacy `transcripts.maxPerUser: false` to disable count-based eviction, so apps can retain complete user histories beyond the default 200 entries [1]. Numeric limits still trim older entries, and retention TTL remains independent. Tests cover retaining 205 entries with no cap, the default 200-entry cap, and legacy configuration merging [2].

Next.js fixed an issue in the Route Info dev tools panel where toggling a route segment boundary like `loading.js` or `not-found.js` didn't update the UI until the modal was closed and reopened [3]. The cause was the segment explorer trie mutating nodes in place, which prevented the memoized view from picking up insertions until remount [4].

The AI SDK @ai-sdk/openai 4.0.60 adds "GPT-6 reasoning configuration updates" [5], with @ai-sdk/azure 4.0.63 and @ai-sdk/amazon-bedrock 5.0.76 updating their OpenAI dependency accordingly [6][8]. These are patch releases with no breaking changes.
