fix: preserve any type in Prettify utility type#8

Without this guard, Prettify<any> was producing { [x: string]: any }
instead of preserving 'any'. This caused issues when using p.any()
in object schemas.
- Add conditional check: any extends T ? T : ...
- Add type-level tests for any() inference

The Prettify type was transforming
anyinto{ [x: string]: any }because mapped types overanyproduce an index signature.This broke inference for
any():type T = Infer<typeof any()>; // was: { [x: string]: any }, should be: any
Fix by adding a guard that preserves
any(andunknown):any extends T ? T : { [K in keyof T]: T[K] } & {}
