feat(compiler): 添加对裸机环境的支持并改进构建配置

Browse Source 
- 更新README描述为C语言裸机环境的自举编译器
- 修改justfile中的构建命令，添加--dev参数并将输出文件名从scc.exe改为scc
- 在AST定义中添加SCC_AST_UNKNOWN节点类型
- 修复位置日志格式化中的类型错误
- 实现标准输出流支持，当输出文件为'-'时输出到控制台
- 支持基于环境变量LANG的语言本地化选择

fix(lexer): 改进标记打印功能

- 修复换行符的显示，将实际换行符显示为"\n"
- 改进文件输出逻辑，支持标准输出流

refactor(build): 更新cbuild工具的包含路径

- 将包含路径从"scc_libs"更改为"scc_include"

test: 添加简单的包含测试用例

- 新增测试文件tests/simple/12_include.c用于测试头文件包含功能
