fix: scan command not reporting scanned files and folders

[st3iny]

The scan command did not log scanned files and folders and did not report stats corretly. Now, it does.

Problem: The ::class path is not starting with a backslash while the event is emitted with a backslash.

Lint failures are not related. Those are up to the maintainers to fix.

/backport to stable30

Lint failures will be fixed by #3859, so a rebase will be necessary afterwards.

The backport to stable30 failed. Please do this backport manually.

@st3iny can you do the stable30 backport?

[provokateurin]

@st3iny can you also add a @noRector for these lines? They were broken by rector refactoring and now rector is trying to change them again.

@provokateurin I just double checked and it is not broken on stable30. We are good. Thanks for the other backport :)
