Include pre-start hook images in pull and config

[cyphercodes]

What I did

• Include distinct pre_start lifecycle hook images in docker compose config --images.
• Include pre_start hook images in docker compose pull and in the image pull path used by up/create.
• Added unit coverage for config image collection, pull option policy propagation, and hook image pull behavior.
