Fix#1524
Root cause
DeepSeek's reasoning models stream reasoning_content alongside content.
Answer ignored it, so follow-up requests failed with 400: The
reasoning_content in the thinking mode must be passed back to the API,
and the thinking text was never shown or saved.
Fix
- Capture reasoning_content from the stream and pass it back to theAPI
on subsequent rounds.
- Persist it with the conversation (new DB column via migrationv2.0.2).
- Render it in the chat UI as a collapsible "Thinking…/Thoughts"panel
above the answer.
Compatibility
Nullable column, omitempty field, UI hides the panel when empty — old
conversations and non-reasoning models behave exactly as before.
