ai_sdk_remote 3.0.0

Optional Vercel AI UI-message stream transport for AI SDK Dart.

3.0.0

• Added the optional Vercel AI UI-message stream transport and typed reducer.
• Added strict SSE framing, cancellation, authentication hooks, and unknown event preservation.
• Added validated UIMessage request conversion, per-request aborts, terminal finish enforcement, and pinned AI SDK reference-server coverage.
• Preserve existing assistant content and prior tool results when a continuation reuses the same message ID.
• The JS reference backend now assigns distinct assistant IDs per turn and survives clients aborting partial request bodies.
