Image Processing Benchmark Runner
==================================

Usage: ./run-benchmarks.sh [scenario] [--fast] [--verbose]

Scenarios:
  all       - Run all benchmarks (60-120 minutes)
  quick     - Fast test run for development (5-10 minutes)
  parallel  - Test parallel processing strategies (20-30 minutes)
  chunks    - Optimize chunk size (20-30 minutes)
  sizes     - Test different image sizes (45-90 minutes)
  stress    - Large-scale stress test (2-4 hours)
  help      - Show this help message

Flags:
  --fast    - Use dry run for faster but less accurate results
  --verbose - Show detailed output

Examples:
  ./run-benchmarks.sh quick
  ./run-benchmarks.sh parallel --fast
  ./run-benchmarks.sh stress --verbose

Results will be saved to: MaddoShared.Benchmarks/BenchmarkDotNet.Artifacts/results/
