This PR adds a comprehensive benchmark suite to compare the performance and memory characteristics of the binary-based CodeBreaker.Bot and string-based CodeBreaker.BotWithString algorithm implementations.

Key Changes

Self-Contained Benchmark Implementation

• Removed dependency on private Azure DevOps feeds by creating local copies of both algorithm implementations
• Added BinaryCodeBreakerAlgorithms.cs and StringCodeBreakerAlgorithms.cs with all core methods
• Created local GameType definitions to eliminate external package dependencies

Comprehensive Comparison Suite

Added 60+ benchmarks in ComparisonBenchmarks.cs covering:

• Core Operations: BlackMatches, WhiteMatches, NoMatches filtering
• Data Access: Peg selection and color conversion operations
• Initialization: Algorithm setup and memory allocation patterns
• Game Types: Game6x4, Game8x5, and Game5x5x4 scenarios
• Data Sizes: Full lists (1000+ values) vs reduced lists (20-200 values)

Performance Insights

Initial benchmark results show clear performance characteristics:

• Binary implementation: ~3.7x faster execution, ~6.4x less memory usage
• String implementation: Better API compatibility, improved code readability

Example comparison for Game6x4 initialization:

| Method                                  | Mean      | Allocated |
|---------------------------------------- |----------:|----------:|
| Binary_InitializePossibleValues_Game6x4 |  20.87 us |  16.25 KB |
| String_InitializePossibleValues_Game6x4 |  76.43 us | 103.23 KB |

Enhanced Documentation

Updated README.md with:

• Detailed usage examples for running specific benchmark categories
• Performance interpretation guidelines and optimization recommendations
• Architecture comparison between binary and string implementations
• Troubleshooting tips and best practices

Easy Execution

The benchmark suite supports targeted execution:

# Compare all implementations
dotnet run -c Release -- --filter "*Comparison*"

# Test specific operations
dotnet run -c Release -- --filter "*BlackMatches*"
dotnet run -c Release -- --filter "*Initialization*"

# Quick validation
dotnet run -c Release -- --filter "*Game6x4*" -j Dry

Benefits

For Developers: Clear performance metrics enable informed algorithm selection based on specific requirements (performance vs readability vs API compatibility).

For Architecture: Memory usage insights help with capacity planning and resource optimization in large-scale deployments.

For Maintenance: String-based algorithms provide better debugging capabilities while binary algorithms offer superior performance for critical paths.

The benchmark suite is now production-ready and provides data-driven guidance for algorithm selection in the CodeBreaker game platform.

Fixes #320.
