Code Review

This pull request updates project dependencies in Cargo.lock, including the addition of wasmtimer and a switch to a git fork for mimalloc. It also modifies the browser runtime to use a CROSS_ORIGIN constant for script loading and introduces logic in the ECMAScript external module to handle script-type exports by creating a namespace object. Feedback was provided to refine the namespace creation logic by using hasOwnProperty during property iteration and checking for an existing default property before assignment to avoid potential bugs.
