Experiments DB Dev 5fcd97f81a analysis(matlab): formalize cross-study (current vs _f) rate comparison

Add make_crossstudy_compare.m producing crossstudy/result.txt +
crossstudy_summary.csv: current control (A2, A2+Naive) and anodal (B2) arms
vs the previous study's a2_f/b2_f, on per-animal success RATE, at full range
(0-9 both) and attempt-matched (current 0-3 vs previous full).

Finding: current > previous for both arms at full range (B2 0.54 vs 0.41
p=0.024; A2+Naive 0.42 vs 0.33 p=0.014) but the gap vanishes/reverses at
matched effort (B2 0.33 vs 0.41 n.s.; A2 0.30 vs 0.33 n.s.) -- a practice/
attempts artifact (~2.7x more attempts/session), not a stronger cohort.
