feat: Implement continuous test execution on file changes in Visual Studio Code

[thabo-moyo97]

Implement a feature in Visual Studio Code that allows continuous test execution for specific test classes when their corresponding application files are modified. When this feature is enabled, any changes to the specified application files will automatically trigger the execution of the associated test classes.

Example

• Enable continuous test execution for TestApp1.
• Modify the App1 application file.
• The TestApp1 test class is automatically executed.
• Enable continuous test execution for TestApp1, TestApp2, and TestApp3.
• Modify the App3 application file.
• The TestApp1, TestApp2, and TestApp3 test classes are automatically executed.
• Modify the App4 application file.
• No tests are triggered since no test classes are listening to App4.

completed and merged through main. Will need code improvement, not familiar with vscode extension development yet so code is just gibberish atm, but it works
