PR fix notes

PR #16000: app/ui: await ensureQueryData in chat route loader

Description (problem / solution / changelog)

The route loader fires ensureQueryData without await, so the component mounts before the cache is populated and briefly shows 'Loading chat...' on every navigation. Adding await makes TanStack Router wait for the data to be ready before rendering.

Fixes #15996

Changed files

  • app/ui/app/src/routes/c.$chatId.tsx (modified, +1/-1)

What is the issue?

When switching from one chat to another, there's a brief "Loading chat..." flash before the messages appear. This happens every time, even if the chat data was already fetched.

Why it happens The route loader for the chat page fires off a data prefetch but doesn't wait for it to complete. The component mounts immediately, finds no data in the cache yet, and renders the loading state for a split second until the data arrives.

Expected behavior The router should wait for the chat data to be ready before mounting the component, so the user sees the messages instantly without any loading flash.
