Eval mobility/pseudo-mobility tweaks; drop unproductive move-ordering experiments.
eval.c: add bishop/rook x-ray pseudo-mobility terms (squares seen past a
directly-attacked higher-value piece), trim pawn-centrality edge penalty
and bishop-pair bonus.
chess.h/dynamic.c/generate.c/search.c/searchsup.c: revert three move-ordering
experiments (recapture bonus, flee-to-safety GOOD_MOVE promotion, ply-2
move-pair bonus) that calibrated with real fail-high signal but never
converted into a measurable node-count or solve-rate win on the curated
suites -- see MOVE_ORDERING_IDEAS.md for the evidence and reasoning behind
each drop. Add MOVE_ORDERING_EVIDENCE_COLLECTION as its own GNUmakefile
flag, independent of PERF_COUNTERS, for any future such harness.
command.c: remove the KING_DEFECT_DUMP-gated evalkingdump command, dead
since the king-safety remine work moved to eval_tune/king_safety_data/.
