feat(backtest): stylized engine over market_snapshots + CLI subcommand

Aggiunge `core/backtest.py`, motore di backtesting stilizzato che gira
sui dati raccolti in `market_snapshots`. Risponde alla domanda:
"se questa config fosse stata attiva nelle ultime N settimane, quanti
lunedì avrebbero superato i filtri e quale sarebbe stato il P/L stimato?"

**Architettura a due strati**:

1. **Filtri di entry — RIGOROSO**: per ogni Monday-14:00-UTC nei
   snapshot ricostruisce `EntryContext` e chiama lo stesso
   `validate_entry()` del live. Output esatto di "cosa avrebbe deciso
   il bot" per ogni settimana, con conteggio dei motivi di skip.

2. **P/L per trade accettato — STILIZZATO**: senza catena opzioni
   storica, stima credito/exit via Black-Scholes con skew premium
   (default 1.5×) per approssimare la vol smile dell'ETH. Re-prezza
   il combo ad ogni tick futuro per simulare i trigger §7
   (profit_take, stop_loss, vol_stop, time_stop, expiry).

**Aggregati nel `BacktestReport`**:
- n_picks / n_accepted / n_skipped_data / n_completed / n_winners
- win_rate, P/L cumulato (USD + % su capitale)
- max drawdown (USD + % di peak)
- Sharpe annualizzato (52 settimane)
- skip_reasons: dict{motivo → settimane bloccate}

**CLI**: nuovo `cerbero-bite backtest --strategy F --from D --to D
--capital N --asset ETH`. Stampa Rich-formatted summary + tabella
motivi di skip. Esempio:

    cerbero-bite backtest \
      --strategy strategy.aggressiva.yaml \
      --from 2026-04-01 --to 2026-05-01 \
      --capital 10000

**Limiti dichiarati**:
- BS + skew_premium ≠ catena reale: i numeri P/L sono **stime ex-post
  per ranking config**, non promesse operative. Buono per dire
  "config A batte config B sui dati reali", non per dimensionare
  capitale.
- skew_premium 1.5× è stato calibrato sui dati Deribit storici
  (smile slope ETH options); va rifinito quando avremo abbastanza
  chain history da farlo empiricamente.

**Tests**: 15 unit test (BS math, monday picks, filter sim,
position outcome simulation, full pipeline su sintetico).
Suite totale: 420 passed.

+"""Stylized backtest engine over ``market_snapshots`` (§13).
+
+Two layers, both pure functions:
+
+1. **Entry-filter simulation** — for each Monday 14:00 UTC tick in the
+   recorded snapshots, evaluate which §2 gates would have passed,
+   reconstructing :class:`EntryContext` from the snapshot.  This part
+   is **rigorous**: it uses the same :func:`validate_entry` the live
+   engine uses, so the output is exactly "what the bot would have
+   decided".
+
+2. **P/L estimation per accepted entry** — since ``market_snapshots``
+   does NOT record the option chain (we only collect spot, DVOL,
+   funding, etc.), credit and exit P/L are estimated via a stylized
+   Black-Scholes model: given ``spot``, ``DVOL`` (as IV), and the
+   strategy's delta target, we solve for the short strike, the long
+   strike at ``width_pct`` distance, and the combo mid-price.  Future
+   ticks are then re-priced under the same model to detect the first
+   exit trigger from §7.
+
+The stylized layer is **intentionally approximate**: it captures the
+geometry of the strategy (DVOL band sets credit, ETH path drives
+exit triggers) but not the second-order effects (chain liquidity,
+borrow rates, exchange fees beyond the 0.03% notional cap, dealer
+hedging skew).  Numbers are good for ranking and tuning, not for
+operational P/L promises.
+
+The engine is deterministic and side-effect-free: it does **not**
+write to SQLite, does not call MCP, does not place orders.  It
+operates entirely on a list of :class:`MarketSnapshotRecord` rows
+the caller has already loaded.
