Check tools part2

[n-peugnet]

• add parallel lint to check for syntax errors
• add phpcs PSR12
• add phpstan doctrine extension (to check DQL and some doctrine magic)

To fix most of PHPCS errors you can run the following command:

composer fix

All of the commands I added are composer scripts that you can check in composer.json:

antilope/composer.json
