Improve Schema type safety

[DadiBit]

What's Changed

No breaking changes. Just a dead-simple helper to improve type safety a bit.

"Full" type-safety like zod or drizzle (maybe, I have never used the latter) could happen, but some major refactoring would be required to work with objects:

• drop name from field class at lower level
• underlying data would be stored as an object of (Anonymous)Fields
• access fields by key name, rather then index

Could you remove pnpm related changes from this PR?
It's not required for this proposal, right?

If you're interested in our package manager, let's work on it as a separated PR. See also: #189

Could you open an issue for this proposal? This is a sub task of #232 , right?

Cool, thanks! I'll be joining to convince everyone that pnpm is the best package manager 😄

It is a PR "subtask" for #232, correct, I will open an issue with proper context and examples as soon as I can.

This is not the final solution, but it should allow for a smoother transition.
