feat: add support for OpenTelemetry messaging/queue system spans

[saviogl]

Adds parsing logic for OTel spans with messaging.system attributes to properly categorize queue operations. Producer spans get 'queue.publish' operation and consumer spans get 'queue.process' operation. The span description is extracted from the span name (e.g., "Sidekiq::Worker" from "Sidekiq::Worker publish").
