Function is_queue_topic_field

internal/cbm/extract_calls.c:1890–1902

Check if a struct-field name identifies a queue/topic target. Cloud SDKs pass the destination via a composite-literal input struct rather than a bare string arg (e.g. Go `SendMessageInput{QueueUrl: ...}`, `PublishInput{TopicArn: ...}`). Case-insensitive so QueueUrl/QueueURL/queue_url all match.
