📄 Description

Related Issues or Context

Summary
Fixes critical issues where Qwen-Thinking models would nest tool calls inside <think> tags or drop them entirely during streaming.

Key Changes

  1. Fix Nested Tags: Force-closes </think> if a tool call starts while reasoning is active.
  2. Fix Dropped Calls: Removed mutual exclusion to allow processing text and tool calls in the same stream chunk.
  3. Fix Duplication: Corrected full_text state management in non-incremental mode to prevent duplicated output.
  4. Optimization: Combined stream yields to reduce overhead.
