Fix reasoning disappearing after streaming completes

A React Native app for the ultimate thinking partner.

The grouping logic was only checking for separate reasoning_message objects,
but streaming creates messages with reasoning as a field. Now it checks both:
1. Separate reasoning messages (server non-streaming format)
2. reasoning field on the message itself (streaming format)

This is a 2-line fix that makes reasoning work in both cases.
