During HMR, `recreateLView()` destroys the old LView and removes its DOM nodes, but never cleans up dehydrated view DOM nodes stored in `LContainer[DEHYDRATED_VIEWS]`. These are SSR-rendered DOM nodes preserved by Angular's hydration system. When the new view renders, both the old dehydrated DOM and the new DOM coexist, causing visible duplication (e.g. `<app-shell>` header/footer appearing twice). Call `cleanupLView` from the hydration cleanup module after `destroyLView` and before `removeViewFromDOM` to remove any remaining dehydrated DOM nodes before the replacement view is rendered. Fixes #66503
