Reasoning
Reasoning models streamreasoning_content deltas alongside content.
Non-streamed calls return it on the message:
<think>…</think> inside
content instead of a separate channel. The server splits it out: the
<think> span is appended to reasoning_content and stripped from
content, so you only ever render one thinking block.
Render reasoning_content in a collapsible block and content as the
answer. In streams both arrive as deltas — accumulate each separately.
