new package for generate queries/mutation/types from OpenAPI spec

[blasdfaa]

Motivation

While existing solutions like openapi-react-query, openapi-stack, and openapi-qraft offer various methods to integrate OpenAPI with TanStack Query, they often rely on code generation, have limited flexibility, or do not fully adhere to TanStack's design philosophy.​

The goal of the new package is to provide a native, declarative, and type-safe way to work with OpenAPI schemas in the TanStack style
