Closes remaining DS-parity gaps from the feature audit:
- ProductRule model (product/collection/vendor/type/tag scoping) with
real server-side enforcement in hold-request.server.ts, plus shaped
availability in availability-request.server.ts. Covers per-product
prep time, cart-content-based slot blocking, and product-restricted
locations in one mechanism. New /app/rules admin page (Growth+).
- Driving-distance delivery zones via Google's Distance Matrix API,
cached like existing geocoding results.
- SHIPPING-only estimated arrival range (transitMinDays/transitMaxDays
on SlotTemplate) — widget shows "Arrives Thu-Sat" instead of a
meaningless ship-out time slot; carried through to the order
metafield write-back.
Storefront widget and POS extension now send cart contents (vendor/
type from cart.js, product ids for Admin-API-resolved collection/tag
rules) to both availability and hold endpoints.
checkout-datetime remains excluded from this deploy pending Shopify's
Network Access approval (unrelated to this work) — re-add from
../checkout-datetime-disabled and redeploy once granted.
