ItemTemplate follows ArcItemTemplate_Load (sb.exe 0x4AABD0): weapon and armor blocks keyed by item type, sheath and stub blocks, and empty equip slot masks read as empty sets. Adds SheathSlot and readHashLabel, which keeps unresolved hashes such as item_skill_used in 195340. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
