 * finalTextCleanerN7.test.ts — N7: EN disclaimer patterns in stripDisclaimers
 *
 * finalTextCleaner.ts aveva 23 pattern IT ma 0 pattern EN.
 * N2 aveva gia' aggiunto L1_HALLUCINATION_EN a liteAutoCorrectBlock,
 * ma stripDisclaimers non aveva mai ricevuto equivalenti EN.
 * Rischio: risposte in EN con "As an AI...", "I don't have access..."
 * passavano la pulizia finale senza essere strippate.
