Detect shells that fail to launch when shell integration injection fails

[Tyriar]

If a shell fails to launch when shell integration injection fails we should allow the user to recover without needing to investigate. Some options:

• Automatically launch a non-injected shell, this could disable terminal.integrated.shellIntegration.enabled but we should be very careful if so, a notification would be better
• Prompt to launch a non-injected shell?

we could even launch the terminal for them with it disabled? that would minimize the impact to the user

Something we don't want to do: Disable without some sort of user prompt because if we shipped a bad update for example all users would have the feature disabled forever unless they noticed.

Maybe the best of both worlds would be to launch a terminal without shell integration while keeping it enabled and inform the user with a notification abt ways to troubleshoot for future launches?

We're thinking to prevent workflow interruption to:

• create a new terminal that doesn't have shell integration enabled
• show an indicator on the terminal tab that contains info about this on hover
• status bar hover action
