Fix item name matching: handle minecraft: prefix in inventory

- equip_item now tries: exact → stripped prefix → fuzzy substring match
- If item not found, error message lists actual inventory contents
- get_inventory strips minecraft: prefix from item names
- Fixes "diamond_sword not in inventory" when item exists as
  "minecraft:diamond_sword"
