refactor: move final legacy result dspark_grid into experiments/legacy_bench_results/

- Move bench_results/dspark_grid_20260707-132641/ to experiments/legacy_bench_results/
- Remove empty bench_results/ directory
- Update README.md, BENCHMARK_WORKFLOW.md, legacy README, and parse_results.py default path
- Update internal report/evaluation paths
