Batch 9/10 visibility polish: surface arsenal and family-zone matchup fields in output

- Add arsenal_hit_boost, arsenal_hr_boost, arsenal_tb2p_boost, arsenal_whiff_risk, arsenal_sample_size
- Add family_zone_hit/hr/tb2p_boost, family_zone_whiff_risk, family_zone_sample_size, pitcher_family_zone_sample_size
- Fix traj_boost key names (hit_adj / hr_adj / tb2p_adj) so trajectory fields are non-None in output
- No math, weights, ordering, or clamps changed — visibility-only patch
