fix(inventory): handle parenthetical descriptions with newlines in item parser

Updated parseItems() to intelligently collapse newlines within parentheses:
- Tracks parentheses depth to handle nested parens
- Replaces newlines with spaces only when inside parentheses
- Preserves newlines outside parentheses
- Prevents double spaces after newline replacement

Example fix:
- Input: 'Books (various magical tomes\n\nhistorical texts)\n\nAlchemy Ingredients'
- Before: ['Books (various magical tomes', 'historical texts)', 'Alchemy Ingredients']
- After: ['Books (various magical tomes historical texts)', 'Alchemy Ingredients']

 /**
  * Parses a comma-separated item string into an array of trimmed item names.
  * Filters out empty strings and handles "None" gracefully.
+ * Smart handling: collapses newlines inside parentheses, preserves them outside.
  *
  * @param {string} itemString - Comma-separated items (e.g., "Sword, Shield, 3x Potions")
  * @returns {string[]} Array of item names, or empty array if none
  *
  * @example
  * parseItems("Sword, Shield, 3x Potions") // ["Sword", "Shield", "3x Potions"]
+ * parseItems("Books (magical\ntomes), Sword") // ["Books (magical tomes)", "Sword"]
  * parseItems("None") // []
  * parseItems("") // []
  * parseItems(null) // []
