Creates a shared useStream instance and makes it available to all
descendant components via Svelte's setContext/getContext.
Call this in a parent component's <script> block. Children access
the shared stream via getStream.
Uses the same context key as setStreamContext/getStreamContext, so both retrieval functions work interchangeably.
