Futility pruning restored. Verified: 647/879 solved, EBF 4.609 @ sn=4M; 684/879 solved, EBF 3.995 @ 20s/move, 1cpu, 256m hash (typhoon_baseline.log). The counter-move table is still written and its stats still tracked (dynamic.c) for diagnostic purposes, but generate.c no longer reads it for move ordering, so it has no effect on search behavior in this commit. lmr_testing/ holds the in-flight graded-LMR + counter-move code (not applied here) with notes on what was already tried and measured, so a future session can resume without re-deriving it.
