📄 Description

Summary

Fixes #23923 (Ref: #23917 Bug 4)

  • Convert Ollama's message.thinking field to <think> tags in the standard content field
  • Generic OpenAI SDKs don't understand reasoning_content and silently drop reasoning tokens
  • Open WebUI's browser middleware already renders <think> tags as collapsible blocks -- fully backward-compatible
