Patch Changes

• bcce2dd: feat(stream-text): expose standalone stream transformation helpers and deprecate the equivalent streamText result methods.

  The new toUIMessageChunk and toUIMessageStream helpers let you convert a streamText stream (or any compatible ReadableStream<TextStreamPart<TOOLS>>) into UI message chunks without going through the result object — useful for custom transports, tests, and other producers of TextStreamPart.

  result.toUIMessageStreamResponse(options) and result.pipeUIMessageStreamToResponse(response, options) can migrate by passing toUIMessageStream({ stream: result.stream, ...options }) to createUIMessageStreamResponse or pipeUIMessageStreamToResponse.

  The new toTextStream helper extracts text deltas from a streamText stream, so result.toTextStreamResponse(options) and result.pipeTextStreamToResponse(response, options) can migrate to createTextStreamResponse({ stream: toTextStream({ stream: result.stream }), ...options }) and pipeTextStreamToResponse({ response, stream: toTextStream({ stream: result.stream }), ...options }).

  result.toUIMessageStream, result.toUIMessageStreamResponse, result.pipeUIMessageStreamToResponse, result.toTextStreamResponse, and result.pipeTextStreamToResponse are now @deprecated. They still work in v7 and will be removed in the next major release. Migration snippets are in the v6 → v7 migration guide.
