/**
 * The editor's own catalog refresh — so the library does not depend on cron.
 *
 * Cron is the wrong single point of failure for this: WP-Cron only fires when
 * someone visits the site, a stalled loopback disables it entirely, and it runs
 * with no user, which is what made the sync silently no-op on a locally
 * connected site (see PatternSync::OWNER_OPTION). The editor, by contrast, is
 * exactly where an empty library is noticed — and it arrives with a logged-in
 * user whose connection resolves without any borrowing.
 *
 * This is NOT a violation of "no editor-facing request may touch the network"
 * (spec 051 FR-001): that rule governs pattern REGISTRATION, which still reads
 * the local cache only and is what the inserter blocks on. This is a separate,
 * explicit request the editor makes AFTER it has loaded, and its result is
 * applied by invalidating the client's pattern cache — never by holding up a
 * render.
