Summary by CodeRabbit
WalkthroughThe generator now tracks blittable field offsets and emits nullable nested view properties. Nested blittable fields use individual serialized slices. Benchmarks and tests now handle absent nested data and verify nullable property types. ChangesNullable nested view generation

Resolve the nullability warnings.
Lines 1282-1283 pass field.NestedSerializableType to a non-null parameter. The preview checks report a possible null argument. Preserve the field-kind invariant explicitly with field.NestedSerializableType!, or restructure the branch so nullable flow analysis can prove it.

Assert the absent child view.
Line 252 verifies only the present-child path. NullValuesRoundTrip sets Child = null, but it does not assert that view.Child is null. A getter that returns a default FixedClassView for a zero offset would pass the current null-case test.
Add Assert.Null(view.Child) in NullValuesRoundTrip.
