spiral/cycle-bridge#50
Checked on local project:
Scenario to check it:

1. Create User entity

/**
 * @Cycle\Entity(
 *     database="core",
 *     table = "users",
 *     repository="App\Repository\Core\UserRepository"
 * )
 * @Cycle\Table(
 *     indexes={
 *          @Cycle\Table\Index(columns={"email"}, unique=true)
 *     }
 * )
 */
class User extends AbstractEntity
{
    /**
     * @Cycle\Relation\HasOne(
     *     target="UserProfile",
     *     outerKey="user_id"
     * )
     */
    public UserProfile $userProfile;

    /**
     * @Cycle\Column(type = "string(180)", name = "email")
     */
    public string $email;

    /**
     * @Cycle\Column(type = "bigPrimary", name = "id")
     */
    protected ?int $id = null;
}

2. Create UserProfile entity

/**
 * @Cycle\Entity(
 *     database="core",
 *     table = "user_profile",
 *     repository="App\Repository\Core\UserProfileRepository"
 * )
 */
class UserProfile extends AbstractEntity
{
    /**
     * @Cycle\Relation\BelongsTo(
     *     target="User",
     *     innerKey="user_id"
     * )
     */
    private User $user;

    /**
     * @Cycle\Column(type = "bigPrimary", name = "id")
     */
    protected ?int $id = null;
}

3. Run command cycle:migrate

    3.1. Check new migration up method:

public function up()
{
    $this->table('users')
        ->addColumn('email', 'string', [
            'nullable' => false,
            'default'  => null,
            'size'     => 180
        ])
        ->addColumn('id', 'bigPrimary', [
            'nullable' => false,
            'default'  => null
        ])
        ->addIndex(["email"], [
            'name'   => 'users_index_email_5eda12d26660e',
            'unique' => true
        ])
        ->setPrimaryKeys(["id"])
        ->create();
    
    $this->table('user_profile')
        ->addColumn('id', 'bigPrimary', [
            'nullable' => false,
            'default'  => null
        ])
        ->addColumn('user_id', 'bigInteger', [
            'nullable' => false,
            'default'  => null
        ])
        ->addIndex(["user_id"], [
            'name'   => 'user_profile_index_user_id_5eda12d264da5',
            'unique' => true
        ])
        ->addForeignKey(["user_id"], 'users', ["id"], [
            'name'   => 'user_profile_foreign_user_id_5eda12d264dfd',
            'delete' => 'CASCADE',
            'update' => 'CASCADE'
        ])
        ->setPrimaryKeys(["id"])
        ->create();
}
