Hi @njoubert-cleverage

A few remarks/questions:

• I added GEMINI.md to make it simpler to work alongside Gemini CLI. I do not know what the official position of Symfony COE about tools like this? It helped me to write unit tests.
• You can get the latest major versions of doctrine/dbal and doctrine/orm with PHP 8.2 and Symfony 6.4 (c.f. the latest jobs) so I was thinking of removing the older versions of these two packages?
• I am going to continue to add unit tests for the remaining classes not yet covered.
