Implement benchmarking and visualization framework

Create a comprehensive benchmarking and visualization framework for algorithm comparison:

## Benchmarking capabilities:
- Execution time measurement
- Memory usage tracking
- Operation counting
- CPU/cache profiling integration
- Scaling behavior analysis

## Visualization components:
- Algorithm execution animation
- Data structure state visualization
- Performance comparison charts
- Time/space complexity visualization
- Big-O growth rate comparison

## Features to implement:
- Benchmark harness for comparing algorithm variants
- Input generation for worst/average/best cases
- Statistical analysis of performance results
- Interactive visualizations for education
- Export capabilities for documentation

## Integration with algorithms:
- Standard interfaces for plugging algorithms into framework
- Annotation system for operation counting
- Hooks for capturing internal state for visualization

This framework will make it easier to compare algorithm implementations, validate theoretical complexity, and create educational materials demonstrating algorithm behavior.
