Confirm minimal AI call returns JSON with title

Sry, somehow assigned this to the wrong person.

This is ready for review. Here's an easy way to QA:

ddev drush php-eval "print_r(\Drupal::service('ai_migration.ai_migrator')->convert('https://example.com'));"

Replace example.com with any url.

Please note that I am aware of the PHPStan issues -- I did not use DI with the logger service in order to quickly get logging in. I can refactor this to DI later.

Looking good @majorrobot and thank you for the easy to follow documentation. Left a few comments and here my tests:

Working URL:

dmundra in ~/workspace/community/ai_migration on branch 3537651-confirm-minimal-ai > ddev drush php-eval "print_r(\Drupal::service('ai_migration.ai_migrator')->convert('https://ndhurandhar.art/art/2025-06/artist-impression-rex'));"
```json
{
  "title": "Artist impression of Rex"
}
```%

Non-existent URL:
