Component-scoped configuration cascade for the breadcrumb family
provideBreadcrumbConfigAt

Description#
Component-scoped configuration cascade for the breadcrumb family. Pass any
combination of feature factories in a parent component's viewProviders
array.
Unlike provideBreadcrumbConfig (root-only), provideBreadcrumbConfigAt
injects the parent injector's CNGX_BREADCRUMB_CONFIG value (resolves
through the priority chain - root provider, library defaults, or another
provideBreadcrumbConfigAt further up) and deep-merges the supplied
features on top. Descendant breadcrumb instances see the merged config;
sibling sub-trees keep the inherited value untouched.
