    *
    * <p>
    * This is the seam that lets a caller in another package (e.g. {@code BeanInstantiator} running a
    * whole-object {@code @ConfigProperties} bind) populate additional fields between field injection and
    * {@code @PostConstruct}, so that a {@code @PostConstruct} method observes the fully-populated object.
    * Keeping the hook here — rather than teaching {@code ClassInfo} about any specific binder — preserves the
    * {@code reflect} package's independence from the {@code inject} package's higher-level binders.
    *
    * <p>
    * Passing a {@code null} hook is exactly equivalent to {@link #inject(Object, BeanStore)}, which is the form
    * all existing callers use.
