* @param options - Configuration options:
* - cacheTag: A version string to append as query param for cache busting
* Example: { cacheTag: 'v1.0.0' } results in '?t=v1.0.0' on all requests
* - deployUrl: Base URL where the host's remoteEntry.json and bundles are located
* This is used to construct the URL for the host's remoteEntry.json and shared dependencies.
* Default is './' relative to the current page. If your host's remoteEntry.json is at a different location, specify it here.
* Example: { deployUrl: 'https://example.com' } results in 'https://example.com/remoteEntry.json'
*
* @returns The final merged ImportMap that was injected into the DOM
