Walkthrough

The function responsible for retrieving field type names from the upstream schema was updated to include an additional lookup step for interface objects when the enclosing type is not found. A new test case was introduced to verify the selection rewriter's behavior with interface objects and concrete type fragments, ensuring correct handling without rewriting.

Changes

File(s)	Change Summary
v2/pkg/engine/plan/abstract_selection_rewriter_helpers.go	Enhanced the logic in fieldTypeNameFromUpstreamSchema to handle interface objects when enclosing type is missing.
v2/pkg/engine/plan/abstract_selection_rewriter_test.go	Added a test case for interface objects with concrete type fragments to the selection rewriter tests.
