When a new file/folder is added to a folder, it is assigned a default name instead of prompting the user to provide one.

### Description

I noticed that when we try to add a new file/folder by selecting a folder in CodeEdit it directly adds file/folder by the name untitled. Shouldn't it allow a blank cursor and let user add name of file and folder.

### To Reproduce

1. Open Any Folder in CodeEdit.
2. Try to add new file/folder from CodeEdit.
3. It adds file/folder by name untitled.

### Suggested Behavior

1. newly created file/folder should have blank place with cursor to allow user to add file/folder name.

### Version Information

CodeEdit: Version 0.0.3-alpha (37)
macOS: 14.3.1

### Additional Context

在 CodeEdit 中開啟一個資料夾，並從專案導覽器新增檔案或資料夾，以重現此行為。追蹤新項目的進入點，並確認建立的項目會進入名稱編輯狀態，欄位為空且游標已就位，而不是使用「untitled」；對檔案和資料夾分別重複這些步驟。
