MessageQueue resolves inherited Object properties as callable modules

Description

The legacy bridge stores lazy callable-module initializers in an ordinary object and reads it by arbitrary module name. Unregistered names such as constructor and __proto__ therefore resolve through Object.prototype; getCallableModule('constructor') invokes the inherited constructor and returns an object although no module was registered. Assigning __proto__ also changes the registry prototype instead of creating a normal module entry.

Expected behavior

Only explicitly registered callable modules should resolve, and every valid string name—including __proto__—should be registrable.

Comienza por el registro de MessageQueue del bridge heredado y el punto de entrada getCallableModule. Comprueba cómo se buscan y asignan nombres arbitrarios, y verifica después que los nombres no registrados no se resuelvan a través de Object.prototype y que se pueda registrar y recuperar cualquier nombre de cadena válido, incluido proto.
