Problem with JSON column

### Bug Report

| Q | A
|-------------------------------------------- | ------
| doctrine-bundle | 3.3.1
|doctrine/doctrine-migrations-bundle" | "^4.0",
|PHP Version | 8.4

#### Summary

Doctrine crashed after created a table with JSON

#### Current behavior

```
root@e3f8cd825c7a:/var/www/html# php bin/console doctrine:migration:diff
[critical] Error thrown while running command "'doctrine:migration:diff'". Message: "assert($options !== null)"
[critical] Uncaught Error: assert($options !== null)

In AbstractSchemaManager.php line 661:

assert($options !== null )
```

#### Expected behavior

It should works ?

#### How to reproduce

In my scenario

I create a simple entity called `test`

```
class MyEntity
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
#[Groups(['get'])]
private ?int $id = null;

#[ORM\Column(type: 'json')]
#[Groups(['get', 'patch'])]
private array $domains = [];
}
```

Then, i try to generate a diff and apply it

```
root@b7e3ffb21f00:/var/www/html# php bin/console doctrine:migration:diff
Generated new migration class to "/var/www/html/migrations/Version20260728055728.php"

To run just this migration for testing purposes, you can use migrations:execute --up "DoctrineMigrations\\Version20260728055728"

To revert the migration you can use migrations:execute --down "DoctrineMigrations\\Version20260728055728"

root@b7e3ffb21f00:/var/www/html# php bin/console doctrine:migration:migrate

```

Reproduce the failure with the shown JSON column entity by running doctrine:migration:diff after applying the generated migration. Start at AbstractSchemaManager.php line 661 and trace the schema comparison that leaves $options null. Done means the second diff completes without the assertion while preserving correct JSON-column handling.
