- Introduce BDN-based runner (AcBinaryVsMemPackBenchmark) mirroring Console's FastestByte scenario; add BdnSummaryAdapter for unified result translation.
- Standardize output: both runners emit .log/.LLM/.output triplets; BDN-native artifacts go under Benchmark/BDN/.
- Simplify CLI: replace granular switches with --serializers; update help and usage.
- Remove legacy benchmark classes; focus on scenario-based approach.
- Rewrite README.md for both AyCode.Benchmark and Console to document dual-runner architecture, output conventions, and dependencies.
- Rotate BINARY_TODO.md; archive closed entries to BINARY_TODO_2026_04.md and BINARY_TODO_2026_05.md.
- Add BINARY_SGEN_OPTIMIZATION.md for SGen per-property emit optimization notes.
- Update comments and docstrings for clarity and maintainability; clarify BenchmarkResult iteration semantics for BDN rows.
