Changelog: Version 0.5.1 -> 0.6.0

Core Architecture

• Replaced Celery/Django-Celery-Beat scheduling with a native Python background threading system.
• Implemented file-based operation locking to prevent concurrent execution of long-running tasks.
• Centralized all configuration defaults into a static PluginConfig class.

Features

• Added SmartRateLimiter with exponential backoff and jitter to handle API rate limits and server errors.
• Added detailed analysis to CSV exports, including token mismatch detection and match threshold recommendations.
• Introduced user-configurable scheduling (timezone and time selection) directly within plugin settings.
• Added "Cleanup Orphaned Tasks" action to remove legacy Celery periodic tasks.

Improvements

• Refactored API data fetching to support robust retries and token refreshing.
• Enhanced fuzzy matching logic with specific support for "token overlap" detection.
• Improved progress reporting via WebSocket notifications for task completion status.
• Added automatic expiration for operation locks to prevent deadlocks.
