Similar to push, we know that pop does not perform interior mutability. Effect.Store here models pop similar to const arr = []; /*...*/; arr[2] = undefined; (writing exclusively to the container, not to any internal elements)

pasted these to BuiltInMixedReadonlyId, which is our read-only JSON-like object kind.
Happy to remove these and refactor later if we prefer to not have duplicates

Adds Array.prototype methods that return primitives or other arrays -- naive type inference can be really helpful in reducing mutable ranges -> achieving higher quality memoization. Also copies Array.prototype methods to our mixed read-only JSON-like object shape. (Inspired after going through some suboptimal internal compilation outputs.) [ghstack-poisoned]
