Prisma GraphQL Decimal Type

Provides a GraphQL scalar type for Prisma's Decimal scalar, wrapping decimal.js. Current stable version is 4.0.4, requires @prisma/client v7 and @prisma/client-runtime-utils v7, and GraphQL v16. It converts decimal values between Prisma's Decimal type and GraphQL. Useful when using Prisma with GraphQL code-first approaches (e.g., NestJS) to avoid serialization issues. It exports GraphQLDecimal scalar and a transformToDecimal function for class-transformer integration.
