Smarter metafield imports with auto-type detection

Importing metafields just got easier. No more guessing metafield types or cluttering your column headers with type specifications.

🔧 Improvements

#

• Metafield type detection – automatically detects types from your Shopify metafield definitions when not specified in column headers.
• Simplified column headers – use Variant Metafield: custom.color_primary instead of Variant Metafield: custom.color_primary [list.metaobject_reference].
• Smart caching – avoids repeated API calls by caching metafield definitions during import runs.
• Cross-object support – works for products, variants, customers, orders, collections, and all other supported object types.
