Great catch, thank you!

Indeed the ECMA-262 doesn't require global object to have immutable prototype; it's the WebIDL spec which makes global objects' [[Prototype]] slots immutable: https://webidl.spec.whatwg.org/#platform-object-setprototypeof. That shouldn't affect the JSC shell of course.

When fixing that we need to ensure that scope resolution is sane when `globalThis.__proto__` is modified, which might get a little tricky.
