feat: update models to qwen3-coder series and optimize routing

- Replace qwen3-235b-a22b with qwen3-coder-plus and qwen3-coder-flash
- Optimize router configuration for different scenarios:
  - default/think/longContext: use qwen3-coder-plus (stronger model)
  - background: use qwen3-coder-flash (faster model)
- Update test cases to validate new model configurations
- Ensure all routing configurations work correctly
