1. Phase2Translator 增加 TPC_ASAN 支持(opt asan 插桩+链接 -fsanitize=address)，配合 clang64 定位 0xbe 崩溃。2. llvmlite/memhub/viperio/viperlib 多处理无界 strcpy/strcat/下溢/递归守卫/栈数组钳制。3. memhub alloc 块尾 canary(MEMBUDDY_CANARY)+check_alive_blocks 校验+chk_stack realloc 扩容。4. TypePrint Ptr(Struct) 类型名截断上限 40→255：含 sha1 前缀类型名(如 bbdf3bbd4c3bc28c.CONSOLE_SCREEN_BUFFER_INFO=42)被截断产生未定义类型引用(llc undefined type)。
