Refactor benchmark suite to use enums for config
Replaced string parameters for layer, opMode, and serializerMode with strongly-typed enums (BenchmarkLayer, BenchmarkOpMode, SerializerSelectionMode) across BenchmarkLoop, Menu, and Program. Updated CLI parsing and menu logic to use Enum.TryParse and return enums. Added XML docs for new enums. Improves type safety, code clarity, and maintainability.
Refactor: split Program.cs into Menu, Output, DTO
Refactored the benchmark console app for modularity:
- Moved all menu logic to Menu.cs (main/settings menus)
- Moved all output/result formatting to Output.cs
- Extracted BenchmarkResult DTO to BenchmarkResult.cs
- Program.cs now only handles orchestration and the benchmark loop
- Moved GetCurrentCharsetName to Configuration.cs
- Removed obsolete Warmup methods from serializers
No functional changes; improves clarity and maintainability.
