Rest And Graphql Request Support

via “graphql query composition and execution”

Send HTTP requests from text files in VS Code.

Unique: Treats GraphQL as a first-class request type within the same `.http` file format, allowing developers to mix REST and GraphQL requests in a single file with shared variables and environments.

vs others: More integrated than GraphQL Playground because queries live in version-controlled files; simpler than Postman's GraphQL support because syntax is plain text and shares the same variable system as REST requests.
