* devops: Product and product attribute mutation tests generated
* feat: Product Mutations implemented and tested
* chore: Linter and PHPStan compliance met
* fix: resolve test failures in product and variation mutation tests
- Removed duplicate requires for payment-method classes (rebase artifact)
- Wrapped bare `attributes` queries in `... on SimpleProduct` inline
fragments (attributes field is on ProductWithAttributes interface,
not the base Product type)
- Fixed attribute label expectations to match factory output (lowercase)
- Fixed relay ID prefix from 'product'/'product_variation' to 'post'
to match WPGraphQL's actual encoding
- Cache WP_Post before force-deletion and re-cache after so the Product
model's type resolver can still determine the GraphQL type in the
response
- Added wp_cache_flush() before asserting product deletion to avoid
false positives from the re-cached post
* chore: fix PHPCS lint errors in mutation files
* fix: resolve CI test failures for attribute and variation mutations
- Fixed ProductVariation type registration in schema filters so the
variation mutation output field resolves correctly
- Renamed attribute slug from 'pattern' to 'fabric' in
ProductAttributeMutationsTest to avoid collision with the pattern
attribute created by ProductAttributeQueriesTest
- Fixed PHPStan errors for redundant is_wp_error checks
- Updated IntrospectionQueryTest
* fix: Huge refactor across schema and unit tests
* - add shipping_method loader in class-core-schema-filters.php
* - Update class-wc-db-loader.php to respect the new SHIPPING_METHOD loader with a `load_shipping_method_from_id()` function
* - Convert Shipping_Method_Connection_Resolver to extend AbstractConnectionResolver
* - Replace resolver for Shipping Methods connection. Remove use of `resolveNode` and replace the resolver with the new connection class `get_connection()` call
* chore: Factory class refactored.
* - update the function that registers Product Types to the Schema to use the value from the `get_enabled_product_types()` as the Type name and the key as the fieldName
* chore: PaymentGatewayQueriesTest refactored.
* chore: WPCS compliance met
* chore: Syntax error fixed.
