[Feature]现在的shell为什么不使用链表的方式来管理历史命令呢，是基于那方便考虑的呢？还有是否考虑为shell增加Ctrl+z/y功能，有些时候使用起来太不方便了

Describe problem solved by the proposed feature
现在存储历史命令的方式是二位数组，且历史命令满了后，需要逐条拷贝移动，如果增加历史命令数量，这里是比较耗时的

Research direction
No file, test, or shell entry point is named. Start by locating the shell history implementation and confirming how its two-dimensional array stores and shifts commands. Clarify whether the scope includes only linked-list history storage or also Ctrl+z/y editing, then define tests and completion criteria before implementation.
