BruceChen 896263acc8 fix: resolve entity tracking, container interaction, and enchantment mapping issues for 1.21
- SpawnEntity packet handler now registers non-player entities via OnSpawnEntity
  for protocol >= 1.20.2 (previously only players were tracked, causing 'entity near'
  to find nothing)
- PlaceBlock gains lookAtBlock option that sends a position/rotation update before the
  block placement packet, fixing containers not opening via useblock
- Enchantment registry IDs are now dynamically parsed from server RegistryData
  (minecraft:enchantment), fixing incorrect enchantment name display in 1.21
- AttributeModifiersComponent uses base SubComponent type to avoid InvalidCastException
  when parsing 1.21-specific attribute subcomponents
