Deprecate "use-sync-external-store" as it doesn't play nice with React 19?

import { useSyncExternalStore } from 'use-sync-external-store/shim/index.js'

It seems that when transpiling this with React 19 support it provides the error

Attempted import error: '__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED' is not exported from 'react' (imported as 'React93').

Looking at the transpiled code (only reference to the usage of the require_use_sync_external_store_shim_development method)

// ../../node_modules/use-sync-external-store/cjs/use-sync-external-store-shim.development.js
import * as React91 from "react";
var require_use_sync_external_store_shim_development = __commonJS((exports) => {
    // ...
    var ReactSharedInternals = React91.__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED;
    // ...

// ../../node_modules/use-sync-external-store/shim/index.js
var require_shim = __commonJS((exports, module) => {
  if (false) {
  } else {
    module.exports = require_use_sync_external_store_shim_development();
  }
});

// ../../node_modules/cmdk/dist/index.mjs
import * as n56 from "react";
var import_shim = __toESM(require_shim(), 1);
...

Solution would be to not use the use-sync-external-store module, which only seems to be used in https://github.com/pacocoursey/cmdk/blob/9827edf89fc663e24188f9d715a0dca01a736d6d/cmdk/src/index.tsx
