syncFeature method
Start background sync for a specific feature. Respects concurrency limits and priority ordering.
Implementation
void syncFeature(String featureKey) {
if (_disposed) return;
if (!_handlers.containsKey(featureKey)) return;
// Add to queue and process
if (!_pendingQueue.contains(featureKey)) {
_pendingQueue.add(featureKey);
_sortByPriority();
}
_processPending();
}
