Patch Changes

• #5599 c9f081a Thanks @penalosa! - fix: add support for wrapped bindings in magic proxy

  currently Miniflare#getBindings() does not return proxies to provided wrappedBindings, make sure that appropriate proxies are instead returned

  Example:

  import { Miniflare } from "miniflare";
  
  const mf = new Miniflare({
  	workers: [
  		{
  			wrappedBindings: {
  				Greeter: {
  					scriptName: "impl",
  				},
  			},
  			modules: true,
  			script: `export default { fetch(){ return new Response(''); } }`,
  		},
  		{
  			modules: true,
  			name: "impl",
  			script: `
  				class Greeter {
  					sayHello(name) {
  						return "Hello " + name;
  					}
  				}
  
  				export default function (env) {
  					return new Greeter();
  				}
  			`,
  		},
  	],
  });
  
  const { Greeter } = await mf.getBindings();
  
  console.log(Greeter.sayHello("world")); // <--- prints 'Hello world'
  
  await mf.dispose();

• #5599 c9f081a Thanks @penalosa! - fix: add support for RPC in magic proxy

  currently Miniflare#getBindings() does not return valid proxies to provided serviceBindings using RPC, make sure that appropriate proxies are instead returned

  Example:

  import { Miniflare } from "miniflare";
  
  const mf = new Miniflare({
  	workers: [
  		{
  			modules: true,
  			script: `export default { fetch() { return new Response(''); } }`,
  			serviceBindings: {
  				SUM: {
  					name: "sum-worker",
  					entrypoint: "SumEntrypoint",
  				},
  			},
  		},
  		{
  			modules: true,
  			name: "sum-worker",
  			script: `
  				import { WorkerEntrypoint } from 'cloudflare:workers';
  
  				export default { fetch() { return new Response(''); } }
  
  				export class SumEntrypoint extends WorkerEntrypoint {
  					sum(args) {
  						return args.reduce((a, b) => a + b);
  					}
  				}
  			`,
  		},
  	],
  });
  
  const { SUM } = await mf.getBindings();
  
  const numbers = [1, 2, 3];
  
  console.log(`The sum of ${numbers.join(", ")} is ${await SUM.sum(numbers)}`); // <--- prints 'The sum of 1, 2, 3 is 6'
  
  await mf.dispose();
