feat: add option to switch to full verification

[ilyaliao]

This PR fixes #53 where form validation stops prematurely due to short-circuit evaluation in the verify() method. Previously, when a field validation failed, subsequent fields would not be validated due to the && operator's short-circuit behavior.

This PR will add an option to switch to full verification.

These are two different strategies: full validation and stopping after encountering an error. We can provide an option during validation to choose the method to use. This avoids destructive updates and is more flexible.

By the way, I'm very happy to see someone using SlimeForm and submitting a PR for it! ☺️

Thanks for the feedback! You're right, having an option to choose validation strategies would be more flexible. I'll work on implementing this approach.
