Mirrors the React integration pattern used by createReactQuery() and
createReactHookForm(): create the adapter once, then bind individual
contracts with rf(contract). Contracts must declare a body schema whose
input is object-shaped. After binding, formOptions(...) and useForm(...)
install the body schema as a Standard Schema validator in the async slot
chosen by validateOn.
Create a TanStack Form adapter factory.
