Prevent _AsValue name collisions in generated Views.
A valid blittable struct can declare a public property named Nested_AsValue. This line then generates another Nested_AsValue property for Nested, which causes a duplicate-member compile error in the generated View. Reserve the _AsValue suffix or report a generator diagnostic before emitting the accessor. Add a regression test for this valid model shape.
