Respect @psalm-internal

[vudaltsov]

Relates to #904.

https://psalm.dev/docs/annotating_code/supported_annotations/#psalm-internal allows to specify a different namespace for an @internal class. Currently cannot update to deptrac >=0.21.1 due to this issue.

And what is broken about this? What is the expected and actual behavior?

[vudaltsov]

I started making a reproducer and realized that I didn't get this right:

If you do so, the marked class cannot be referenced by any class outside its layer

Thank you for this feature!

Glad to hear, it solved itself. I will check your other issue for making internal checks configurable when I have time
