Identifie les agents zombies (busy >1h sans completion via started_at + status), error_count_last_hour > 5, ou drift quarantine (quarantined_until > now).
Donne 3 recommandations concretes en markdown bullet points avec actions SQL utilisant SEULEMENT les 2 tables autorisees ci-dessus.

## Identification des anomalies

### 1. Agents zombies (busy >1h sans complétion)
```sql
SELECT a.id, a.name, a.status, r.id AS task_run_id, r.status AS task_status, r.started_at
FROM agencecom.agents a
JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
WHERE a.status = 'busy'
  AND r.started_at < NOW() - INTERVAL '1 hour'
  AND r.completed_at IS NULL
  AND r.status NOT IN ('completed', 'failed');
```

### 2. Agents en erreur (error_count_last_hour > 5)
```sql
SELECT id, name, status, error_count_last_hour
FROM agencecom.agents
WHERE error_count_last_hour > 5;
```

### 3. Agents en dérive de quarantaine (quarantined_until > NOW())
```sql
SELECT id, name, status, quarantined_until
FROM agencecom.agents
WHERE quarantined_until > NOW();
```

## Recommandations concrètes

- **Libérer les agents zombies**  
  Forcer l’échec de la tâche en cours et remettre l’agent en `idle`.  
  ```sql
  BEGIN;
  -- Marquer la tâche comme échouée
  UPDATE agencecom.agent_task_runs
  SET status = 'failed',
      completed_at = NOW(),
      error_message = 'Zombie tué par le monitor – plus d’1h sans complétion'
  WHERE id IN (
      SELECT r.id
      FROM agencecom.agents a
      JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
      WHERE a.status = 'busy'
        AND r.started_at < NOW() - INTERVAL '1 hour'
        AND r.completed_at IS NULL
        AND r.status NOT IN ('completed', 'failed')
  );
  -- Libérer l’agent
  UPDATE agencecom.agents
  SET status = 'idle',
      current_session_id = NULL
  WHERE id IN (
      SELECT a.id
      FROM agencecom.agents a
      JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
      WHERE a.status = 'busy'
        AND r.started_at < NOW() - INTERVAL '1 hour'
        AND r.completed_at IS NULL
        AND r.status NOT IN ('completed', 'failed')
  );
  COMMIT;
  ```

- **Mettre en quarantaine les agents trop erratiques**  
  Placer en quarantaine 30 minutes tout agent dont `error_count_last_hour > 5`.  
  ```sql
  UPDATE agencecom.agents
