Add ability to define field level configurations outside of JSX?

[juanvilladev]

Hello guys,

I've drafted PR #1201 introducing a new buildFieldConfigurations function to createFormHook (React) that enables developers to define field logic outside of JSX while maintaining full type safety.

This feature offers significant benefits for complex form implementations:

• Separates validation/listener logic from UI components
• Provides centralized configuration for field behavior
• Maintains complete type safety through TypeScript generics
• Supports both static and dynamic field configurations!
• Improves code organization and maintainability for larger forms

I believe this addition would be particularly valuable for applications with complex validation requirements or large-scale forms. I'd appreciate your feedback on this approach and any suggestions for refinement before proceeding further.
Looking forward to your thoughts!

After talking with @juanvilladev on Discord, we decided on an API to do this:

const firstNameOpts = fieldOptions({
    // Infer the types from `formOptions`
    ...formOpts,
    // Add field-specific APIs
    validator: {/* ... */}
});

We'll track more progress in #1201 with the API updates. Thanks for this idea!
