"""
Pipeline stage management system.

This module provides a comprehensive framework for managing pipeline stages including:
- Base classes for stage implementation
- Stage registry for dynamic stage discovery
- Dependency resolution for proper stage ordering
- Built-in stage definitions for common operations

The stage system supports:
- Multi-threaded task processing
- Task deduplication and retry logic
- Dependency-based stage ordering
- Dynamic stage registration and discovery
- Comprehensive statistics and monitoring
