feat(parser): 添加声明列表支持并重构解析逻辑
- 添加 SCC_AST_DECL_LIST 节点类型用于表示声明列表 - 实现 scc_ast_decl_list_init 函数来初始化声明列表节点 - 重构 scc_parse_declaration 函数以支持逗号分隔的多个变量声明 - 分离类型说明符解析到独立的 scc_parse_declaration_specifiers 函数 - 支持 typedef 和多变量声明如 'int a, b;' 和 'int a = 1, b = 2;' - 在 ast_dump 中添加对声明列表节点的打印支持 refactor(ast): 统一使用 scc_vec_foreach 宏替换手动循环 - 将 ast_dump.c 中的多个手动索引循环改为使用 scc_vec_foreach - 提高代码可读性和安全性 - 避免索引越界错误 fix(parser): 修复语义分析中结构体符号表冲突 - 为结构体、联合体和枚举符号名添加前缀避免命名冲突 - 使用 '$S_'、'$U_'、'$E_' 前缀分别标识结构体、联合体和枚举 refactor(log): 统一终止处理方式 - 将 log_exit 替换为 log_abort 以更准确反映行为 - 更新相关依赖模块的实现 style(parser): 移除未使用的参数和清理代码 - 在 argparse.c 中添加 (void) 参数注释处理未使用的参数 - 清理 parse_expr.c 中未使用的函数声明 - 优化 parse_type.c 中的错误处理流程
