fix: implement topBitSetTerminatedArray, fix nbt TAG_End, fix entity_equipment

- Implement topBitSetTerminatedArray decoder/encoder with MSB continuation
- Fix nbt.Tag.Decode to handle TAG_End at root level (fixes 1.8 slot NBT)
- Remove 228 now-passing decode failure tests, keep 10 still failing
- EntityEquipment now works correctly across all versions
