fix: AST_PARAMETER 增加数组元素类型字段 + 五子棋集成测试

Browse Source 
问题: 函数参数声明 i64[N] 只在 TypeInfo 存储数组信息, AST_PARAMETER
仅存 TypeKind(TYPE_ARRAY), 丢失元素类型和大小, 导致 sema 将参数
数组误判为 i32[N], codegen 生成 void GEP 而崩溃。

修复:
- AST_PARAMETER 新增 arr_elem_type/arr_elem_struct/arr_size 字段
- parser 传入 parse_type_expr 的完整数组信息
- sema 将数组信息从 AST 节点复制到 Symbol
- codegen 为数组参数生成正确的 LLVMArrayType

附加: 45_gomoku.l — 5x5 五子棋双AI对弈, 测试数组/函数/循环/字符串
