feat: add support for OpenTelemetry messaging/queue system spans

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").
