/**
 * Regression test for #747: WordPress importer must clear the URL pattern
 * cache after creating new collections so that public routing immediately
 * resolves the new patterns. The original symptom of #747 (the execute
 * step reading a stale DB-persisted manifest) is no longer possible —
 * the manifest is built fresh per admin request and never cached — but
 * the URL pattern cache is still per-isolate, and prepare->execute
 * happens in two separate requests that may or may not share an isolate.
