Pouch & Paper

📝 Improvements

• Changed pouch and crop sack breaking behavior:
  — When broken while sneaking (shift), the block now drops full pouches/sacks instead of individual seeds/crops (one pouch per 4 units).
  — Any leftover seeds/crops less than 4 units drop as individual items.
  — Breaking without sneaking continues to drop all seeds/crops as individual items.
• This change improves inventory management and consistency with stacking logic.
