Debugging a script should dot-source it into the session

[daviwil]

ISE parity request: when launching a script in the debugger, it should be dot-sourced so that its contents become available in the console session after the script finishes executing.

Question: should this be configurable even if I provide a separate option to always create a new PowerShell session each time the debugger starts?

Looked into this briefly, seems that the missing piece is that I need to pass an additional parameter to PSCommand.AddScript, a boolean that causes the script to be evaluated into the local scope:
