4.3.2

What's Changed

Bug Fixes

• Add missing retailer display attribute to each package object (e.g. "retailer": "Amazon"), derived from a display-name map with title-case fallback. The README had always advertised this field but the code never emitted it.
• Key summary.by_retailer off the new retailer field so counts use human-readable names ({"Amazon": 2, "eBay": 1}) instead of raw email domains ({"amazon.com": 2}).
• Fix README JSON example: correct retailer_code value from "amazon" to "amazon_com" to match actual emitted value; add a note explaining that when only the carrier sends the notification email, retailer will reflect the carrier, not the original store.

Note: retailer_code is unchanged (still amazon_com, usps_com, …) to avoid breaking existing automations. The by_retailer summary key shape changes from raw domain to display name — update any templates that read by_retailer['amazon.com'] to by_retailer['Amazon'].
