2.0.0-beta.42 - npm Install Hotfix

v2.0.0-beta.42 is a one-fix hotfix for a crash that only reproduced when alchemy was installed from npm:

ReferenceError: Cannot access 'bindWorkerAsyncBindings' before initialization
  at node_modules/alchemy/src/Cloudflare/Workers/Worker.ts:684:13

Worker.ts forms import cycles with WorkerAsyncBindings.ts and WorkerRuntimeContext.ts, and it passed their exports directly into Platform(...) — reading them at module-load time. When Bun enters the cycle from the other side (which happens with the npm package layout, but not in the local workspace), those references are still in their temporal dead zone and the import crashes.

beta.42 wraps both hook arguments in arrows so they resolve at call time instead of module-load time (#378):

} = Platform(WorkerTypeId, {
  onCreate: bindWorkerAsyncBindings,
  createRuntimeContext: makeWorkerRuntimeContext,
  onCreate: (resource, props) =>
    bindWorkerAsyncBindings(resource as Worker, props),
  createRuntimeContext: (id) => makeWorkerRuntimeContext(id),
});
