useBuyerJourneyIntercept and block_progress deprecated in checkout UI extensions

As of checkout UI extensions API version 2026-07, the useBuyerJourneyIntercept hook and block_progress capability are deprecated; existing extensions keep working on current versions but removal lands in a future release. Migrate business-rule enforcement to server-side cart and checkout validation Functions.

Action note

Inventory checkout UI extensions using useBuyerJourneyIntercept or block_progress and rebuild that logic as cart/checkout validation Functions (or discount Functions for code rejection).
