fix(optimize): add TARGET fallback + enrich score feedback for GEPA

benchmark.sh: fall back to  when ATLAS_OPTIMIZE_TARGET unset
score.py: track find_optimal_crossing and SA direct as separate
  scorecard examples with diagnostic context for reflector
gate.sh: add positional-arg fallback for ATLAS_OPTIMIZE_TARGET

Build: N/A (config & Python shims only)
