Easier product category metafield migration

Migrating products with category attributes (like color pattern or material) between stores used to require setting up metaobject definitions, metafield definitions, and metaobject entries on the destination store first. Now Altera handles all of that for you.

🔧 Improvements

• Automatic metafield definition setup – Altera enables the required product category metafield definitions on the destination store during import.
• Automatic metaobject creation – metaobject entries for category values like “solid” or “cotton” are created if they don’t already exist.
• Validated category values – category attribute values are checked against Shopify’s product taxonomy before creating them.
