AdventureTents v109 - Smithing Table Upgrade Support
Added:
- Shapeless recipe: paper + iron_ingot -> Tent Upgrade Template (borrowed sentry armor trim smithing template)
- Smithing transform recipe: Template + carrot_on_a_stick + iron_ingot -> Medium Tent Upgrade
- Mirrored both recipes and both recipe advancements for hostile runtime.
Notes:
- Smithing base accepts any carrot_on_a_stick by design; downstream logic should validate atent custom_data when used.
- Template is a real smithing template item id so it fits the left slot.
