This PR rewrites `module.js` to use a native ES6 `class` instead of `Class.extend()` - the same old inheritance helper that was removed from `node_helper.js` in #4147. The normal module API stays the same: modules still use `Module.register({...})`. Internally, `Module.create()` now creates a named subclass for each module, copies over a cloned definition, and only calls `init()` when it is actually a function. Outcome: one less file in the browser bundle, no more magic `_super()` wiring, better stack traces, and tests for the module creation path that did not exist before. `module.js` is also now a plain class with no external dependencies - an intentional step towards `export default Module` when browser scripts eventually move to native ES modules. Since these changes touch the core of how modules are created, I'd appreciate a close review and any feedback on edge cases I may have missed.
