Function getTargetFromTree

getTargetFromTree<T = Partial<TreeNode>>(
    tree: T[],
    target: any,
    idKey?: keyof T,
    equalFunc?: EqualFunc<any>,
    childrenKey?: keyof T,
): T | null
在树中查找目标节点（深度优先）

Find a target node in the tree (depth-first).
Type Parameters
- T = Partial<TreeNode>
  节点类型 / node type
Parameters
- tree: T[]
  树数组 / tree array
- target: any
  目标值，用于与节点 id 进行比较 / target value to compare with node id
- OptionalidKey: keyof T = ...
  表示节点 id 的字段名 / field name for node id
- OptionalequalFunc: EqualFunc<any> = ...
  自定义相等比较函数 / custom equality function
- OptionalchildrenKey: keyof T = ...
  子节点字段名 / children field name
Returns T | null
找到的节点或 null / found node or null
