Adds tracing, telemetry, and observability to an assistant-ui backend.

Also covers rendering collected spans with @assistant-ui/react-o11y headless primitives (SpanResource, SpanPrimitive Root/Indent/CollapseToggle/StatusIndicator/TypeBadge/Name/Children, SpanByIndexProvider, SpanData/SpanState) mounted via useAui/AuiProvider from @assistant-ui/store. Use for missing or empty traces, edge vs nodejs runtime telemetry, serverless flush issues, or trace waterfalls.

Use when asked to "review this proposal", "give feedback on this doc", "help me review this RFC", or when presented with a document that needs structured feedback. Handles markdown files, GitHub gists/issues/PRs, and other text formats. Chunks proposals intelligently, predicts reviewer reactions, and produces feedback adapted to the proposal's format.
Search live Stream SDK documentation for Chat, Video, Feeds, and Moderation. Look up how a Stream React/iOS/Android/Node/Flutter/Unity/Angular hook, component, or method works. Answer how-to questions about any Stream SDK across every framework and version. Triggers on 'docs', 'documentation', explicit SDK tokens (Chat React, Video iOS, Feeds Node, Moderation), and 'how do I ... in <framework>' phrasing.
