FLAW: Logger Misleads About Data File Creation Upon Mac CMD+Q Quit

[SeeYangZhi]

When running the app on macOS, if a user quits the app using CMD+Q immediately after loading the app for the first time, without executing any commands, no data file is saved. However, the logger misleadingly suggests that a data file has been created, even though this is not the case.

Steps to Reproduce:

1. Run the app from scratch (with sample data provided).
2. Do not execute any commands.
3. Immediately quit the app using CMD+Q (macOS shortcut).
4. Observe that no data file is saved upon quitting the app.

Expected Behavior:

• The logger should not indicate that a data file has been created unless the file has actually been written to disk.
• The data file should either be saved automatically when quitting the app (CMD+Q) or the logger should correctly indicate that no file has been created.

Observed Behavior:

• The logger outputs a message suggesting that a data file has been created even though no file exists.
• May refer to the logger code in MainApp.java

Additional Context:

• When using the exit command to close the app, the data file is saved correctly.

I think that the data file should be saved when the user CMD Qs
