[suggestion] use a good graphql library

[macrozone]

This is not really a feature request, but I suggestion to avoid a wide category of bugs. But it would also wastly simplify extending graphql request.

at the moment, unchained still uses hand-written schemas and resolvers. This approach is not sound (type safe) and can lead to bugs like #525 or any other type-missmatch.

There are good "code-first" approaches to write graphql. Unfortunatly many of those are not created with 100% type-safety in mind. An exception is https://pothos-graphql.dev/

Pothos has a builder api and can actually guarantee type-safety on arguments and resolvers, including proper null/non-null checks (if strict mode is on, which is mandatory for any library/framework imho).

Additionaly, unchained could wrap and expose pothos api to projects using unchained which would wastly simplify extendig the graphql-api of unchained and enforce correctness.
