bvandeusen 432e0bd2a0 Show Qwen3 thinking output in chat as collapsible Reasoning block
Ollama streams message.thinking tokens alongside message.content when
think=True — previously silently dropped. Now forwarded end-to-end.

Backend:
- llm.py: ChatChunk type gains "thinking" variant; stream_chat_with_tools
  yields ChatChunk(type="thinking") for msg.thinking chunks before content
- generation_task.py: thinking chunks emit "thinking_chunk" SSE events
  (not added to content_so_far — not persisted to DB)

Frontend:
- types/chat.ts: Message.thinking?: string (session-only, not from DB)
- stores/chat.ts: streamingThinking ref; thinking_chunk handler accumulates
  chunks; on done, thinking carried into committed Message object then cleared
- ChatMessage.vue: collapsible <details class="thinking-block"> shown for
  messages that have .thinking content (collapsed by default)
- ChatView.vue + ChatPanel.vue: live thinking block in streaming bubble —
  open while only thinking is flowing, auto-collapses when content arrives;
  typing indicator hidden while thinking is active
