 * Generate HMR code using Angular's ɵɵreplaceMetadata for components,
 * and simple field-swap + invalidation for directives/pipes.
 *
 * The applyMetadata callback dynamically copies all ɵ-prefixed static
 * fields (ɵcmp, ɵfac, ɵdir, ɵpipe, etc.) from the newly compiled class
 * to the old class reference that Angular's runtime is tracking.
 *
 * For components, ɵɵreplaceMetadata then merges the old/new definitions
 * and recreates matching LViews in the component tree.
 *
 * For directives and pipes, ɵɵreplaceMetadata does not support them, so
 * we fall back to a full page reload via import.meta.hot.invalidate().
