Shopify CLI Fixes Silent Loopback Rejection

Your local notifications server was being ignored, but this patch fixes that.

The Shopify CLI has shipped a fix for a silent but frustrating bug: setting `SHOPIFY_CLI_NOTIFICATIONS_URL` to a local `http://` loopback URL was silently discarded, sending the CLI to the production CDN instead [1] [2]. This patch allows HTTP URLs on loopback hosts, with broader IPv6 matching options [3]. Separately, a fix resolves a reauthentication deadlock after a preview store is claimed, where `shopify store auth` would stop in `throwIfPreviewStore` and refuse to recover the session [4] [5]. The old behavior kept the stale preview session, causing repeated errors on `store info`; now the recovery command can actually run. Both fixes landed via merges, and the loopback patch is the one to verify if you rely on local notification previews.

Action items

→ Update your Shopify CLI to include the loopback HTTP fix if you test notifications locally Shopify/cli [plan]
→ Test the preview store reauth flow after claiming a store to confirm the fix Shopify/cli [monitor]
