feat(流程图): 画流程图不用再拖框连线——点箭头上的 + 加一步,判断自动分出是 / 否,排版全自动

原来要从节点库拖框、对准连接点拉线、自己摆位置,还能画出断线和孤立的框;
画布上全是彩色圆角块,交上去的却是平行四边形和菱形。现在照画布稿 FlowEdB:
- 图存成一棵结构树(顺序 / 判断 / 循环),开始、结束固定在两头,排版是纯函数
- 每根箭头上一个 +,点了选输入 / 输出 / 处理 / 判断 / 循环;点框直接改字,右上角「删除」
- 形状照国标流程图,画布、缩略图、交给 AI 的 Mermaid 是同一套;缩略图配色跟着画布改
- 已保存时间、撤销、重做挪到工具栏,「清空画布」收进「⋯」;空框交不上去
- 去掉 vue-flow 三个包(编辑器打包后 16 KB),删掉没人进的 /flowchart 页

2026-10 之前交的图是 vue-flow 格式,只能看缩略图、载不回画布;旧草稿键名不同,不去碰。
