refactor: Enhance workflow system flexibility and convert to English

## Major Changes

### Workflow Architecture Enhancements
- **Simplified pre_analysis definition**: Removed overly specific JSON examples
- **Added flexibility principles**: Emphasized task-driven approach over template copying
- **Enhanced implementation_approach**: Added four design principles and clear field descriptions
- **Converted all Chinese content to English**: Improved international accessibility

### Agent Documentation Updates
- **code-developer.md**: Updated flow control execution to emphasize four flexible context acquisition methods
- **code-review-test-agent.md**: Simplified context gathering process description with practical examples

### Key Improvements
- **Flexibility over rigidity**: Removed mechanical template copying tendency
- **Clear separation**: pre_analysis for context gathering only, no implementation actions
- **Practical examples**: Added dependency task summary reference patterns
- **Consistent language**: Full English documentation for better collaboration

## Benefits
- Restored system flexibility for diverse task requirements
- Clear guidance without prescriptive templates
- Better international accessibility
- Maintained structural integrity while improving usability
