Serendipity 9a53d97274 feat: 字符串类型 + 字面量 + print_str
- 新增 TYPE_STR 类型 (i8* 指针)
- lexer: 双引号字符串字面量 + str 关键字
- parser: TOK_STR_LIT → AST_LITERAL_EXPR(str_val)
- sema: print_str 内置函数注册 + 字符串拼接类型检查
- codegen: GlobalStringPtr 生成字符串常量,print_str → printf("%s")
- 新增集成测试 07_hello_str.l

基于 Codex 分析报告 P0 建议。
