移除了独立的ast_builtin.h头文件，将内置类型定义整合到现有结构中， 同时修复了类型初始化函数命名不一致的问题。 BREAKING CHANGE: 原有的ast_builtin.h头文件已被移除， 相关内置类型声明已重构为新的接口形式。 fix(parser): 修复表达式解析中的位置信息处理 确保条件表达式和逗号表达式的解析正确获取并传递位置信息， 避免在语法树构建过程中丢失源码位置。 refactor(ir): 修复IR转储中的类型转换问题 添加必要的类型转换以防止整数溢出，并优化代码格式以提高可读性。 feat(parser): 添加表达式解析测试套件 引入全面的表达式解析测试框架，覆盖从基本表达式到复杂嵌套表达式 的各种场景，确保解析器功能的正确性和稳定性。
