fix: disable reasoning in translation by default

- Add 'none' to ReasoningEffortOption type definition
- Set reasoning_effort to 'none' in translation assistant settings
- Update enableReasoning check to exclude 'none' value in parameterBuilder.ts
- Update Qwen thinking middleware to properly disable thinking when reasoning_effort='none'
- Ensure translation and other scenarios with reasoning_effort='none' correctly disable all reasoning features
