It might not be obvious to users (especially as it changed with the new adapters) that they should run using Debug mode to get some functionality from the inspector (navigating to files as they select widgets).

#4876 is for deciding (and documenting) the differences between Run/Debug (which should probably be based on specific features rather than arbitrarily what comes over the VM Service) but in the short-term we should do something to avoid confusion from users that don't realise navigation only works in Debug mode.

As a minimum, we should warn users opening the inspector that they should use Debug mode, but we should also evaluate other options (such as a hotfix that connects the VM Service for noDebug mode, or forcing noDebug mode off in the extension and intercepting breakpoints/pause-on-exception requests).
