test: add e2e tests for toResolverOutput with all field types
Test that toResolverOutput produces types matching TailorDB introspection: - Nested objects (userInfo, metadata) - File fields (avatar) - Forward relations (ownerID, owner) - Backward relations (detail from ProfileDetail, comments from ProfileComment) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
