 * knowledgeGapBlockN8.test.ts — N8: EN signal patterns in KNOWLEDGE_GAP_SIGNALS
 *
 * knowledgeGapBlock.ts aveva KNOWLEDGE_GAP_SIGNALS solo in italiano.
 * Se l'utente scrive in EN ("who is the current CEO?") nessun pattern matchava
 * e l'agente non veniva forzato a usare web_search prima di rispondere.
 * Fix: +9 pattern EN (temporal/version/price/person/statistics).
