#span_name ⇒ String

Build OTel-compliant span name for GraphQL spans

Formula per SPAN_NAME_PATTERNS.txt Section 7 (observability):

"{operationType} {operationName}"  e.g. "query MyQuery"
Falls back to just "{operationType}" when no name, or "graphql" when both absent.

Returns:

  • (String) —

    The span name
