Update repo configs from https://getscaffold.dev/

[AlexSkrypnyk]

Download the latest code from Scaffold repo (actual code, not the release).

• Update composer.json with the structure from Scaffold. Preserve the values of the existing fields, but order the fields as per Scaffold's composer.json. Add missing fields.

• Update the Symfony command to use the file structure of CLI Command from the scaffold repo.

• Update tests to use new traits from Scaffold instead of a HelperTrait.php. Use only traits that are required.

• Update CI to run with coverage

• Add Renovate config from Scaffold

• Add/update all GitHub actions and configs to be per Scaffold

• Update readme to use the structure from Scaffold, including the generated logo (circle). Transfer the usage examples into the readme structure from Scaffold

• Update Box config

• Add PHPStan config and fix all newly found violations

• Do not create docs folder and CI action - this project is too small to have extensive docs.

Make sure that CI passes.

@AlexSkrypnyk Can you explain more about 2 point. Or give maybe some kind of example. And also there is a lot of issues related to phpstan(185), do we need to fix them all?

Re 2 - please see https://getscaffold.dev/php/cli-command.html

just need to update the code structure to reflect what is in the scaffold - the command loader , app loader, src, tests

re phpstan - please fix all violations
