fix: visible item stride 2→4 (confirmed from raw field dump)

Browse source 
RAW FIELDS dump shows equipment entries at indices 284, 288, 292, 296, 300
— stride 4, not 2. Each visible item slot occupies 4 fields (entry +
enchant + 2 padding), not 2 as previously assumed.

Field dump evidence:
  [284]=3817(Reinforced Buckler) [288]=3808(Double Mail Boots)
  [292]=3252 [296]=3823 [300]=3845 [312]=3825 [314]=3827

With stride 2, slots 0-18 read indices 284,286,288,290... which interleaves
entries with enchant/padding values, producing mostly zeros for equipment.
With stride 4, slots correctly map to entry-only fields.
