feat: [Coda] 完整实现Code Evaluator功能模块

本次提交包含Code Evaluator的完整功能实现，涵盖以下主要特性：

核心功能：
- 实现Code Evaluator的IDL定义和模板验证功能
- 支持Python和JavaScript代码的语法验证和安全检查
- 添加代码执行、调试和测试接口
- 实现MockEvalTargetOutput接口和JSON模拟数据生成

数据层改进：
- 优化EvaluatorOutputData结构，支持RetVal和stdout字段解析
- 重构Runtime接口架构，从基础设施层迁移到领域组件层
- 完善Evaluator版本管理和数据转换逻辑

安全性增强：
- 集成全面的安全验证，检测危险函数、模块和恶意模式
- 实现语言特定的验证规则（Python和JavaScript）
- 添加大小写不敏感的语言类型验证

测试和调试：
- 完善冒烟测试脚本，支持debug-python场景
- 修复Python f-string语法错误和编码问题
- 优化测试请求头配置和代码内容模板

接口优化：
- 移除冗余的Runtime接口，直接使用组件接口
- 修正evaluator_id与evaluator_version_id的混淆问题
- 分离evaluator和evaluator_version的描述字段

此次合并涵盖了Code Evaluator从设计到实现的完整开发周期，确保功能完整性和代码质量。
