将 `is_next_line` 内联函数重命名为 `lex_parse_is_endline` 并新增 `lex_parse_is_whitespace` 函数，统一用于词法解析中的字符分类。同时加强多个解析函数的输入参数断言，提升代码健壮性。 此外，修正了 `lex_parse_skip_whitespace` 中的逻辑错误，并优化部分注释和控制流结构。 feat(pprocessor): 初始化预处理器模块并添加基础功能实现 新增预处理器模块 `pprocessor`，包括宏定义、条件编译状态管理以及基本的指令解析框架。实现了标识符解析、空白跳过、关键字查找等功能，并初步支持 `#define` 指令的对象类宏替换。 该提交还引入了一组测试用例，覆盖多种宏展开场景及边界情况，确保预处理器的核心行为符合预期。
