Modernize data carriers to records and add primary constructors

Convert 14 data carrier classes to records:
- VillagerInfo, MapIcon, EnchantmentData: non-positional records (mutable properties)
- ForgeMod, SkinInfo, VillagerTrade, Node, Response: positional records
- CommandNode: sealed positional record
- CommandArgumentDescriptor: readonly record struct
- ColorRGBA: record struct (multiple constructors preserved)
- RecipeConfig, Recipe, BannerLayer: non-positional records

Add primary constructors to 6 classes:
- DataTypes, Protocol18Terrain, Protocol18Forge, ItemMovingHelper,
  LastSeenMessageList, Acknowledgment, SuggestionTooltip
