assistant-ui Update

Always consult assistant-ui.com/llms.txt for the latest API.

Upgrade in two passes. First make the AI SDK and its assistant-ui adapter compatible, then update assistant-ui and apply its API migration. Read the relevant references before editing because a direct jump can cross several deprecation windows.
