+Add Web API and CF Worker adapter intialized constants for aggressive tree-shakers
+
+For example with the web-api adapter:
+
+```ts
+// Instead of just:
+import '@shopify/shopify-api/adapters/web-api';
+
+// You can now also import:
+import { webApiAdapterInitialized } from '@shopify/shopify-api/adapters/web-api';
+import { shopifyApi } from '@shopify/shopify-api';
+
+// And check the adapter is initialized, which forces bundlers to keep the import
+if (!webApiAdapterInitialized) {
+  throw new Error('Failed to initialize web API adapter');
+}
+```
