Disable phpstan?

phpstan produces a lot of false-positive alerts.

I'm considering to turn it off in CI.

Let's add Rector to the project. Then we could use Rector + Phpstan for fixing type errors. Also you can disable some fuzzy checks like https://github.com/buggregator/trap/blob/master/phpstan-baseline.neon#L1019

I think Rector may break our elegant code style.
Let's add it without CI, as a composer command. And without changes in SRC because I'm coding a big feature in progress and I don't want to have conflicts 🙀

After local testing we will consider adding it in CI
