Subject: [PATCH] fix: disable recordInputs to prevent Langfuse media upload
 timeout

When images are included in chat messages, the AI SDK telemetry with
recordInputs: true sends base64 image data to Langfuse. Langfuse then
attempts to upload these images to media storage, causing 1m31s timeouts.

Setting recordInputs: false prevents this while still capturing user
text input via setTraceInput().
