+## 补记（自定义窗默认模式对调 + 文件夹弹窗选择）
+
+- 用户反馈：① 自定义窗默认应为「发送到会话」且排第一，「新建对话」第二；② 项目文件夹的
+  父目录+名称双输入太麻烦——要像 DSH 加工作区那样弹资源管理器式位置选择窗。
+- 实现：① CustomPane 默认 mode='existing'、按钮顺序对调（发送到会话在前）；② 文件夹选择
+  改用宿主 ctx.workspaces.pickDirectory()（本机为原生 IFileDialog，真实 Windows 文件夹选择窗，
+  与 DSH 加工作区同款）：新建项目面板 = 路径显示 + 「选择位置…」按钮（必选，留空不可保存）；
+  绑定弹窗「更改」= 直接弹窗选择、选中路径即项目文件夹；取消手输表单与 mkdir 依赖。
+- 验证（probe-batch7.cjs，桩 pickDirectory）：默认模式按钮0=发送到会话且选中、会话行默认可见、
+  分组行默认隐藏 ✓；新建面板路径显示+选择按钮、桩返回路径回填、保存后 folders 持久化 ✓；
+  绑定弹窗「更改」写入选中路径 ✓；functional-diag 全 20 STEP（STEP20 按新顺序重写）
