Fixed the "cannot import name '_download_progress'" error by:

Adding a shared progress_tracker instance in processor/init.py
Exposing public functions that wrap the ProgressTracker methods
Removing direct access to private _download_progress variable
Fixed the "'QueueItem' object has no attribute 'retry_count'" error by:

Updating the QueueItem class in queue/models.py to use retry_count instead of retries
This matches the field name used in the queue manager's implementation
