📘 Description

Add a consumables shop in Citizen Of Arcanis, managed by a bot NPC, where players can purchase items like health potions, ammo, or temporary buffs.
The shop should be interactive, allowing the player to spend in-game currency to acquire consumables that directly affect gameplay.

---

✅ Acceptance Criteria

• Create a shop NPC (bot) that:
  • Spawns in a fixed, accessible location.
  • Displays an interactive shop interface when the player interacts with it.
• Implement a consumables catalog including (at minimum):
  • Health recovery items (e.g., potions or medkits).
  • Ammo or weapon repair kits (if applicable).
  • Temporary buffs (e.g., increased damage, speed, or defense).
• Deduct in-game currency from the player’s balance when buying items.
• Purchased consumables must be added to the player’s inventory and usable immediately.
• The bot should have a basic idle animation or interaction feedback (e.g., greeting text).

---

⚠ Technical Notes

• Reuse or extend the existing inventory and currency systems.
• The shop should be modular, allowing future addition of more consumables or cosmetic items.
• Ensure purchases are validated to prevent exploits (e.g., buying with insufficient funds).
• The bot must be non-combatant and only function as a vendor.
