/**
* WP 7 Abilities API registration for This Is My URL - External Link Control.
*
* Exposes the broken-link checker's most recent scan as a discoverable,
* REST/AI-invokable read-only report. The ability reads the stored results
* of the last scan; it does not start a scan, so it returns instantly and
* makes no outbound HTTP requests of its own.
*
* @package TIMU_ELC
* @since 1.6149
