refactor: collapse-expand support align option

[Aarebecca]

• 树图中节点展开收起支持配置 align 选项(默认为 true)

开启该选项时，展开收起操作始终保持目标元素位置不变（避免丢失目标）

---

• Node expansion and collapse in tree graph supports configuring 'align' option (default is true) (Avoid losing the target)

When this option is on, the Expand and Collapse action always keeps the target element position unchanged

Relative Issue: #6494
