Phase 4 hardening: status CLI, lock file, backup job, hash enforce, pooling, real bias

Sei interventi mirati sui rischi operativi rilevati nell'audit
post-Fase 4. 317 test pass, mypy strict pulito, ruff clean.

1. status CLI: legge SQLite reale e mostra kill_switch, posizioni
   aperte, environment, config_version, last_health_check, started_at.
   Sostituisce il placeholder "phase 0 skeleton".

2. Lock file single-instance: runtime/lockfile.py acquisisce
   data/.lockfile via fcntl.flock al boot di run_forever; un secondo
   container fallisce subito con LockError.

3. Backup orario nello scheduler: nuovo job APScheduler 0 * * * *
   chiama scripts.backup.backup_database + prune_backups.

4. config_hash enforce su start: il CLI start verifica l'integrità
   del file (enforce_hash=True). Mismatch → exit 1 prima di toccare
   stato. dry-run resta enforce_hash=False per debug.

5. Connection pooling MCP: RuntimeContext espone un httpx.AsyncClient
   long-lived condiviso da tutti i wrapper (limits 20/10
   connections/keepalive). aclose() chiamato in run_forever finale.

6. Bias direzionale reale: deribit.historical_close +
   deribit.adx_14 popolano TrendContext con spot a 30 giorni e
   ADX(14) effettivi. Sblocca bull_put e bear_call. Quando i dati
   storici mancano l'engine emette alert MEDIUM e cade su no_entry
   in modo deterministico.
