Module planning 

FFT Planning Module

This module provides an advanced planning system for FFT operations, combining caching, serialization, and auto-tuning to optimize performance. It builds on the functionality provided by the plan_cache and plan_serialization modules.

Key features:

• Unified planning interface for different FFT backends
• Multi-dimensional FFT planning
• Adaptive plan selection based on input characteristics
• Integration with auto-tuning for hardware-specific optimizations
• Support for both runtime and ahead-of-time planning
• Plan pruning and management to optimize memory usage
