Insert Bundle Unbundle

Inserts a Bundle/Unbundle pair for the selected wires. The selected wires are bundled into one cluster in top-to-bottom order, unbundled again, and reconnected to their original source and sink terminals, so the data flow is unchanged.

Limits: a selected wire may have only one downstream terminal (no branches). A wire with branches is reported as an error and the diagram is left unchanged.

Inputs:

• QD Launch VI Ref - the VI QuickDrop was launched from; its block diagram selection is used (normal use).
• Diagnostic VI Path - when not empty, the VI at that path is opened instead and every wire on its diagram is processed, then the VI is saved (testing and batch use).

Outputs:

• error out - reports an error when the selection is not made of wires, holds fewer than two wires, or contains branches.
• changes made? - whether the diagram was modified.

The undo transaction is managed by the caller (the QuickDrop plugin template).

对选中的多条 wire 插入一对 Bundle/Unbundle：把选中的 wire 按自上而下的位置顺序 Bundle 成一个簇，再 Unbundle 回来并接回原来的源端子与下游端子，数据流保持不变。

限制：每根选中的 wire 只能有一个下游端子（无分叉）。存在分叉时报错并放弃，不改动框图。

输入：

• QD Launch VI Ref - QuickDrop 启动所在的 VI，取其程序框图的 Selection List[]（正常使用方式）。
• Diagnostic VI Path - 非空时改为打开该路径的 VI，并对该框图内所有 wire 操作，结束时保存该 VI（测试/批处理用）。

输出：

• error out - 选中对象不全是 wire、少于 2 根或存在分叉时返回错误。
• changes made? - 是否实际改动了框图。

Undo 事务由调用方（QuickDrop 插件模板）管理。
