refactor: move legacy bench_results into experiments/legacy_bench_results/

- Keep only bench_results/dspark_grid_20260707-132641/ in original location
- Move all other historical results to experiments/legacy_bench_results/
- Add README.md explaining the archive contents
- Update root README.md and BENCHMARK_WORKFLOW.md path references

+# Legacy Bench Results Archive
+
+This directory contains historical benchmark results that were originally stored under `bench_results/` before the `experiments/` layout was introduced.
+
+Only `bench_results/dspark_grid_20260707-132641/` remains in the original location per project decision; everything else was moved here for archival.
