DDGameWrapper had an off-by-16 size assertion (0x6F00 vs actual allocation
0x6F10); the 0x20-byte tail is unzeroed unknown padding. Fixed struct field
and size assertion.
WABox never had a Drop implementation so it was purely a leak-by-design
wrapper with no safety value. Remove it entirely and replace all uses:
- WABox::alloc(...).leak() → wa_malloc_struct_zeroed::<T>()
- WABox::from_value(val).leak() → wa_malloc_struct::<T>() + ptr::write(p, val)
