- lexer: TOK_STRUCT, TOK_DOT 关键字和运算符
- ast: AST_STRUCT_DECL/STRUCT_INIT/FIELD_ACCESS 3 种新节点
- parser: struct 声明 + .field 访问 + Name{field:val} 初始化
- sema: struct 类型符号表，字段类型解析，初始化字段检查
- codegen: LLVMStructType + extractvalue/insertvalue 字段操作
- 新增集成测试: 12_struct.l, 13_struct_nested.l
- 基于 Codex 分析报告 P0 #4
所有 P0 功能已全部完成。
