Previously the 5 peer rows were macro-only (per-task null), sourced from
BarunLM-35M's comparison table. This refresh reproduces all 5 with the same
harness (0-shot, seed 1234) on lm-eval 0.4.13, giving each a full 9-task
breakdown. Adds barunlm_published_macro and macro_delta_vs_barunlm_published
fields to expose the gap between my 0.4.13 macros and the source's 0.4.12
comparison-table macros (material for the larger models: LFM2.5 +0.124,
pythia-70m +0.091, pythia-160m +0.066; small models track closely).
