  Buy and sell items at shops.

  Find a shopkeeper NPC and talk to them to open their shop. While
  browsing a shop, these commands are available:

  browse      List all items for sale with buy/sell prices
  list        Same as browse
  buy <item>  Purchase an item with credits (use # to buy by number)
  sell <item> Sell an item from your inventory for credits
  leave       Exit the shop and return to conversation

  Shops buy items at a lower price than they sell them. Some items
  cannot be sold back.

  Shopkeepers can be found throughout the world:
  - General Store: Town Square (sells tools and supplies)
  - Smithy: Forge (sells weapons, armor, and tools)
