This PR addresses a security vulnerability where InventoryItem could be initialized with invalid data, potentially leading to incorrect calculations or exploits.

It adds strict validation in InventoryItem.__init__ to ensure:

  • sku and batch_id are non-empty strings.
  • current_stock is a non-negative integer.
  • daily_burn_rate is a non-negative number (int or float).
  • expiry_date is a datetime.date object.

It also adds a root .gitignore file to improve repository hygiene by excluding __pycache__ and other artifacts.

Tests were verified using pytest balancer/ and a reproduction script.
