fix: honor NotNull and DisallowNull nullability attributes#2334
Merged
Conversation
Already honored MaybeNull (read) and AllowNull (write) to widen a non-nullable typed member to nullable. Add the symmetric narrowing: - NotNull on a nullable-typed source member treats the read value as non-nullable, so no null guard is emitted. - DisallowNull on a nullable-typed target member treats the write as non-nullable, so a null source is guarded/skipped.
