Updates Environment#getGlobalDeclaration() to only resolve "globals" if they are a true global or an import from react/react-dom. We still keep the logic to resolve hook-like names as custom hooks. Notably, this means that a local `Array` reference won't get confused with our Array global declaration, a local `useState` (or import from something other than React) won't get confused as `React.useState()`, etc.
I tried to write a proper fixture test to test that we react to changes to a custom setState setter function, but I think there may be an issue with snap and how it handles re-renders from effects. I think the tests are good here but open to feedback if we want to go down the rabbit hole of figuring out a proper snap test for this.

React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
