Type Alias Effectify<C>

Effectify: {
    [K in FnKeys<C>]: C[K] extends (...a: infer A) => infer R
        ? (...a: A) => Effect.Effect<Awaited<R>, DomainError, never>
        : never
} & { inner: C } & { [K in Exclude<keyof C, FnKeys<C>>]: C[K] }

Maps every method of C to an Effect-returning method, preserving non-fn members.
