OpenAPI Snippet Builder

Build a code snippet for an OpenAPI operation. Scope: JSON spec only (not YAML), get/post/put/patch/delete only, request-body example from example field. Authentication, parameters (path/query/header), server variables, $ref schemas, and operationId collisions are not handled — generated snippets are a starting point, not a finished client.
