Add make_matched_effort.m: pick the current-study day cutoff whose per-animal
cumulative attempts best match the previous (_f) study's full-span total
(~405 attempts/animal -> current days 0-3), then fit the paper LME on both.
Two variation folders (data.csv + analyze.m + result.txt):
variations/prev_f_full/ b2_f vs a2_f, days 0-9 (24 rats)
variations/matched_current_d0_3/ Box-B2 vs Box-A2, 0-3 (6 rats)
At matched cumulative effort both show a significant positive stim x day
interaction (prev p=0.008 +0.56/day; current-0-3 p=0.004 +10.2/day) -- the
tDCS acceleration replicates at equal practice, though the count slopes are
not directly comparable across datasets given differing attempts/session.
