Importing Fusion with Wally breaks `Scope` type generics

[s-wick]

Importing the Wally package and using wally-package-types generates this file (fusion.lua):

local REQUIRED_MODULE = require(script.Parent._Index["elttob_fusion@0.3.0"]["fusion"])
export type Animatable = REQUIRED_MODULE.Animatable 
export type UsedAs<T> = REQUIRED_MODULE.UsedAs<T>
export type Child = REQUIRED_MODULE.Child 
export type Computed<T> = REQUIRED_MODULE.Computed<T>
export type Contextual<T> = REQUIRED_MODULE.Contextual<T>
export type GraphObject = REQUIRED_MODULE.GraphObject 
export type For<KO, VO> = REQUIRED_MODULE.For<KO, VO>
export type Observer = REQUIRED_MODULE.Observer 
export type PropertyTable = REQUIRED_MODULE.PropertyTable 
export type Scope<Constructors > = REQUIRED_MODULE.Scope<Constructors >
export type ScopedObject = REQUIRED_MODULE.ScopedObject 
export type SpecialKey = REQUIRED_MODULE.SpecialKey 
export type Spring<T> = REQUIRED_MODULE.Spring<T>
export type StateObject<T> = REQUIRED_MODULE.StateObject<T>
export type Task = REQUIRED_MODULE.Task 
export type Tween<T> = REQUIRED_MODULE.Tween<T>
export type Use = REQUIRED_MODULE.Use 
export type Value<T, S = T> = REQUIRED_MODULE.Value<T, S >
export type Version = REQUIRED_MODULE.Version 
return REQUIRED_MODULE

All types are exported correctly except for Scope, whose generic is broken, as it relies on the Fusion type which is not exported in the entry point file (init.luau):

type Fusion = Types.Fusion
...
export type Scope<Constructors = Fusion> = Types.Scope<Constructors>

Using the Fusion.Scope type in VSCode with the LuauLSP yields the following type error:

TypeError: Type parameter list is required Luau[1018](https://luau-lang.org/typecheck)

---

The simplest fix to the issue is to just export the Fusion type from init.luau:

export type Fusion = Types.Fusion

And fixing the Scope type in fusion.lua:

export type Fusion = REQUIRED_MODULE.Fusion
export type Scope<Constructors = Fusion> = REQUIRED_MODULE.Scope<Constructors >

This resolves the error, but is overwritten with updates to the package.
