chore: more specific return type for chunk() method

[rela589n]

Follows from #350

PR Summary

• Modified Return Type in chunk Method
  This PR updates the type of data that the chunk method returns. Previously, it could return a list that might be empty. Now, it ensures that the list returned will always contain at least one item. This adjustment improves the method's reliability and predictability in our system.

I think there are some new errors to fix.

[rela589n]

Do you mean this CI error?

Unfortunately I could not get my local environment ready for the development (If I remember correctly, if I try to run tests on the main branch, some of them fail) yet

without this @var annotation psalm won't be able to infer the fact that chunk is never empty when it is yielded

[rela589n]

Actually this didn't help either, because psalm treats T somewhat awkwardly.

Threrefore, I have somewhat rewritten the implementation into following variant so that both psalm and phpstan are satisfied:

$chunk[] = $value;

if (count($chunk) >= $size) {
    ++$chunkIndex;

    yield $chunk;

    $chunk = [];
}

@drupol , could you help me with this, since right now I'm not sure what I'm expected to do in order to get this PR merged?

Sorry for the long delay, I'm quite busy with this end of year and I don't have much time left for my open-source projects sadly.

Here, it looks like there are code style stuff to update.
Your changes are also introducing new static analysis issues.

Are you able to run the tests on your local machine so you can fix them locally and commit/push when it's done?

It's all right, take your time

Here, it looks like there are code style stuff to update.

I have updated the code so that all checks have passed now.
Once you have some bit of time, please review it.

Thank you,
Yevhen
