添加了 SCC_ARGPARSE_ERR_PNT_DEFAULT 错误类型用于默认操作处理， 实现了 scc_argparse_spec_setup_choices 函数支持枚举选择， 重构了错误处理流程使返回值更加一致。 修复了长选项名称匹配的逻辑错误。 feat(lexer): 添加换行符和注释符号的词法标记 新增 SCC_TOK_ENDLINE 和 SCC_TOK_SHARP 标记类型， 改进词法分析器对换行符和井号的识别处理。 feat(scc_core): 添加常用宏定义 添加 scc_min 和 scc_max 宏定义提供基础数值比较功能。 feat(main): 实现编译器主程序和命令行接口 创建主程序入口实现完整的编译流程， 集成预处理器、词法分析、语法分析和IR生成模块， 添加AST和IR输出功能支持调试查看中间表示。 chore(build): 配置项目构建依赖关系 创建 cbuild.toml 配置文件定义项目包信息和依赖库， 建立编译器各组件库之间的依赖关系管理。
