Feature Request: Open new screencast tabs when new browser windows or tabs are opened

Is your feature request related to a problem? Please describe.
The current behavior of screencast in VS Code Edge Dev Tools can be confusing for users. When new browser windows or tabs are opened, they are not visible in the UI and require the user to click the "Toggle Screencast" button to see them. However, doing so will replace the currently shown tab with the new target, which may not be the desired behavior.

Describe the solution you'd like:
I would like a new screencast tab be opened within VS Code whenever a new browser window or tab is opened during a screencast. This would allow users to see all open instances/targets in the screencast without having to toggle the screencast on and off or lose the view of the previously shown tab.

Describe alternatives you've considered:
One alternative could be to show a notification or pop-up within the VS Code UI whenever a new instance/target is opened during a screencast. However, this may not be as intuitive as having a separate screencast tab for each instance/target.

Additional context:
This feature would improve the usability and user experience of the screencast feature in VS Code Edge Dev Tools. It would make it easier for users to see all open instances/targets without interrupting their workflow. Thank you for considering this request.

No files, tests, or entry points are named in the issue, so begin by locating the screencast implementation and how browser targets map to VS Code tabs. Done means newly opened browser windows or tabs receive separate screencast tabs without replacing the existing view; verify behavior for multiple targets.
