open sketches in the current window, if no code has been written yet

Description

It would be great if Processing didn't need to open a second window if you run it first, then load a project (either directly or using the "open recent" function).

Expected Behavior

Loading a project with an empty editor loads the project in the current editor instance.

Current Behavior

A second Processing instance is created for the loaded sketch code.

Steps to Reproduce

1. Open processing by directly running the application
2. Load a project

Your Environment

• Processing version: 4.0b8
• Operating System and OS version: Win10 pro 21H2
• Other information:

Possible Causes / Solutions

首先在 Processing 应用程序中复现该行为：使用空编辑器启动它，然后直接加载项目，并通过“open recent”加载项目。跟踪这些入口点的编辑器窗口处理逻辑，并让现有窗口在没有代码时加载 sketch；当不再创建第二个 Processing 窗口且正常加载仍能工作时，即表示完成。
