Explicit `=sink` calls such as `Isolated[T].=sink` can delegate to a field type like `float`, which has no attached sink op. In that case `replaceHookMagic` leaves the builtin `mAsgn` call in place. `genMagicExpr` did not lower that shape, which caused the regression. Mapping `=sink` to `nkSinkAsgn` and other builtin assignment hooks to `nkAsgn`.
