PoC: Make zod optional

[scottrippey]

GroqD is a query builder with 2 main features: strong output types, and runtime validation of input types.

This PoC is to determine if we can make runtime validation optional. Reasons:

• If we were able to add strong input types, then it's reasonable to say that runtime validation would be redundant
• Eliminates Zod dependency (majority of this package currently)
• Allows any "runtime validation" library to be used, or none if the schema is trusted
• This would need to be a major version bump

Task list:

• [x] Create new API with similar structure to existing API
• [x] Eliminate Zod validations
• [ ] Introduce "generic" validation types that are compatible with Zod (eg with signature like { parse<T>(input: unknown): T })
• [x] ~Ensure "inferred schema" can be compiled to a *.d.ts file, to alleviate perf issues~
  • Update: this cannot be accomplished
  • Possible alternatives include manually-typing the schema (and performing a cross-check against inferred types) or finding a performant alternative

Update: this will be completed as part of groqd with the groq-builder package
