Refactor benchmarks to use typed enums for engine/mode
Replaced string-based identifiers for serializer engine, I/O mode, and dispatch mode with strongly-typed enums (BenchmarkEngine, BenchmarkIoMode, BenchmarkDispatchMode). Added BenchmarkEnums.cs with ToDisplay() helpers for consistent output. Updated all benchmark implementations, DTOs, and output logic to use enums. Removed obsolete string constants from Configuration.cs. Merged allocation measurement methods in BenchmarkLoop.cs for clarity. Improves type safety, maintainability, and output consistency.
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.
